This is an appeal from a Final Decree of December 23, 1981, issued by the Court of Common Pleas of Luzerne County, Orphans’ Court Division, which dismissed objections to a Petition for Adjudication and Account.
Israel Schwarzbarth died testate on December 17, 1965, and his Will and Codicils were probated on December 31, 1965. Among the assets of his estate was a trust, created out of the residuary estate, the income of which was to be paid to his widow, the executrix, Goldie Schwarzbarth (hereinafter “Goldie”).1 Mrs. Laura Freiman, decedent’s adopted daughter and the appellant here, filed objections to the account on November 18, 1969 and amended objections on October 18, 1978, claiming that she was entitled to a share of the trust property.2 The basis for her claim was that *194Goldie had failed to comply with the terms of the trust and had thereby forfeited her interest therein.3
The matter was heard before the Orphans’ Court which found that the requirements set forth in decedent’s Will, relating to the trust, had been complied with and entered an Adjudication and Decree Nisi to that effect on November 12, 1981. Appellant filed a motion for leave to file exceptions nunc pro tunc to the Adjudication and the Decree. The Orphans’ Court, on December 23, 1981, entered a Final Decree, which while granting the motion to file exceptions nunc pro tunc, dismissed the exceptions in their entirety.
Paragraph 2, Subsection (a) of Israel Schwarzbarth’s Will, executed on February 23, 1965, and on which the appellant’s claim is predicated, provides as follows:
To pay the net income therefrom periodically, but not less than quarterly, to or for the benefit of my wife, GOLDIE, during her life or for so long as she shall retain the surname of SCHWARZBARTH, whichever event shall first occur.
Subsection (b) of Paragraph 2 of the Will was altered by Codicil dated June 25, 1965, and provides that,
“Upon the occurrence of either of the two events mentioned in Subparagraph (b) of this Item of my Will, the said Trust shall terminate and the Trustee shall distribute all the undistributed principal and income, free of Trust, in three equal shares, with one of the said shares to go to my daughter, LAURA, another of the said shares to my daughter, MAXINE, if they are then living, and third of the said shares shall be cut up into as many parts as I have grandchildren then living, that is to say, children of my said daughters, LAURA and MAXINE, with each of the said grandchildren to take per capita. In the event, however, that either of my daughters, LAURA or MAXINE, should not survive the occurrence of either of the two events mentioned in Subparagraph “A” of this item, *195then the share of such deceased daughter as she would have received had she survived, shall be paid to her issue, per stirpes, free of Trust.”
Appellant contends that Goldie’s remarriage to A. David Fried on May 18, 1969, in and of itself, or, in the alternative, the occasional use of her marital surname constitutes noncompliance with the condition set forth in subsection (a) which provides that the income of the trust shall be distributed to Goldie “during her life or for so long as she shall retain the surname of Schwarzbarth ____” (emphasis added). Therefore, appellant contends that since Goldie has not “retained” the surname of Schwarzbarth within the terms of decedent’s Will, Goldie’s life estate therein has been forfeited and the principal and undisposed income should be distributed pursuant to the terms of subsection (b) of the second paragraph of the probated Will.
The Orphans’ Court, after determining that the intention of the testator was unclear from the actual language utilized in his Will, looked to extrinsic evidence and found that Goldie had retained the surname of Schwarzbarth in the manner and to the extent intended by the decedent. For the following reasons we affirm the holding of the Orphans’ Court.
The process of testimentary adjudication has been well-established by the Pennsylvania Supreme Court.
It is, of course, a cardinal rule that a will is to be construed according to the intent of the testator. Where a court feels that it can with reasonable certainty ascertain the intent of the testator through examination of the will itself, the court generally does not look to matters external to that document. Where, however, a court cannot feel such confidence in distributing the estate by reference to the will only, ... it is proper and necessary to inquire into the circumstances of the testator at the time of execution of his will and other evidence which bears on intent. And if even then a court is unable to say with reasonable certainty what the testator intended, resort is had to the canons of construction.
*196Taylor’s Estate, 480 Pa. 488, 494, 391 A.2d 991, 994 (1978) (citations omitted).
Looking to this process, the appellant argues that the testator’s intent may be ascertained from the actual words of the Will without resort to extrinsic evidence. We disagree. When examining the phrase “for so long as she shall retain the surname SCHWARZBARTH____” it is unclear whether the testator intended to penalize his widow’s remarriage by requiring her to forfeit her right to life income by remarriage, or whether he intended merely to require her to use the Schwarzbarth surname as her own in order to maintain her eligibility as income beneficiary. The instant case is one envisioned by the Supreme Court where the Court cannot feel confidence in distributing the estate by reference to the terms of the Will alone, as the testator’s intent is shrouded in ambiguity by the literal terms of the Will. Taylor’s Estate, supra. We must therefore resort to extrinsic evidence to clarify the intention of the testator with respect to the trust estate and to determine whether Goldie’s use of the Schwarzbarth surname complied with this intent.
It has long been held in Pennsylvania that examination of prior wills is helpful in determining the intention of the testator. Thus, in Williamson’s Estate, 161 Pa.Super. 106, 53 A.2d 869 (1947), this Court held:
Where there is such an ambiguity in a Will as to justify consideration of extrinsic evidence former Wills executed by testator may be considered to throw light on his intention.
161 Pa.Super. at 110, 53 A.2d at 871.
The 1965 Will, in effect at the time of testator’s death, revoked a prior Will, dated August 26,1957, which provided for a trust with a life estate to Goldie and which contained, inter alia, the following language:
FOURTH: (a) I give, devise and bequeath all of the rest, residue and remainder of my estate, real, personal or mixed, wheresoever and whatsoever, unto my Trustees hereinafter named, in Trust, nevertheless, to hold the *197same in Trust, and to collect the income therefrom and, after paying all proper expenses, taxes and charges incident to the management and administration of the Trust, to pay GOLDIE, until she shall attain the age of Sixty-five (65) years, or until she shall remarry, whichever event shall first occur. (Emphasis added).
Therefore, the testator’s immediately preceding Will had expressly and unambiguously provided for the forfeiture of his widow’s interest in the trust in the event of her remarriage. That language, which was eliminated in the probated Will, demonstrates that the testator was capable of expressing an intention to cause a forfeiture under the circumstances of remarriage. His failure to have carried that provision over demonstrates an intention different than that manifested in the 1957 Will. Instead, he chose to free Goldie to remarry, subject only to the condition regarding the Schwarzbarth name.
Other evidence presented also indicates that the testator did not intend for his widow to forfeit her life estate upon remarriage. The testator had no male heirs. Both the widow and the scrivener testified that the testator was preoccupied with the continuation of his name. During the course of the 20 years during which the Schwarzbarths were married, the testator became convinced of his wife’s devotion and loyalty and his only concern was that his name live on. As the scrivener explained, the change from prohibition of remarriage to continuation of the surname Schwarzbarth reflected “a deep genuine feeling by the decedent toward his wife of love, affection and appreciation.” Furthermore, because of the 30 year difference in their ages, the testator was aware that Goldie would probably remarry. Therefore, we conclude that remarriage was not what the testator wished to prohibit and that under the terms of the Will, Goldie did not forfeit her life estate upon her remarriage. The right to receive the income of the trust was subject only to the retention of the Schwarzbarth name.
*198We must now determine the testator’s actual intent surrounding the use of the phrase “for so long as she shall retain the surname of SCHWARZBARTH____” Appellant strongly urges this Court to interpret this phrase as requiring exclusive and continuous use. Upon review of the evidence presented at trial, and the circumstances surrounding the testator at the time of execution of the Will, we conclude that the testator did not intend this phrase be given such a strict construction.4
Almost all of the extrinsic evidence presented in the instant case reveals a close, devoted arid trusting relationship between the testator and his wife. During the testator’s later years when he was ailing and unable to conduct his business, Goldie assumed the duty of its supervision and oversight. In this regard, all parties to the controversy testified that the success of testator’s business ventures was due in large measure to the efforts of Goldie Schwarz-barth. Testimony by the scrivener of the probated Will established that over the course of the many years of marriage, the testator came to trust and believe in the loyalty of his wife. Accordingly, the testator revoked his prior Will, which contained an absolute forfeiture provision, and in its place created a life estate for Goldie subject only to the condition that Goldie “retain” the Schwarzbarth surname.5
*199In light of this evidence, we agree with the Orphans’ Court that the testator must be deemed to have understood that Goldie would encounter some difficulty in maintaining the Schwarzbarth surname in each and every transaction following remarriage. Rather, the testator, through the use of the phrase in question, was asking that his widow perpetuate the Schwarzbarth name in the community in which it was known in order to give it viability and currency, and did not intend to create any hardship for his widow in the event of her remarriage.
Evidence presented at trial indicates that Goldie utilized the Schwarzbarth surname in many aspects of her private and public life. The Schwarzbarth surname appears on her driver’s license, social security health insurance card, personal checking account, and numerous credit cards, both old and new. In addition, Goldie has exclusively utilized the Schwarzbarth surname in the Harvey’s Lake, Luzerne County area where the Schwarzbarths resided during their marriage. Accordingly, the surname appears with regard to her real estate holdings in the Harvey’s Lake area. Furthermore, Goldie testified that in her ongoing relationships with her acquaintances, neighbors, community and friends in the Harvey’s Lake area, she holds herself out to be “Mrs. Schwarzbarth.” With respect to Goldie’s use of the Fried surname, the appellant produced documents which are largely official in nature, such as voting records and bank accounts, appearing most often in connection with Goldie’s present husband’s business transactions.
We conclude, therefore, that Goldie perpetuated and “retained” the Schwarzbarth surname in accordance with the testator’s intent. She maintained the currency of the surname in the area in which it was known. To require exclusive use of the name would be contrary to the intentions of a man who had a loyal and rewarding relationship with his wife.
Additionally, we note that when construing conditions in wills, a reasonable construction must be given in *200favor of the beneficiary. In Davis Estate, 275 Pa. 126, 118 A. 645 (1922), the Pennsylvania Supreme Court stated,
[W]hether there has been a performance or breach ... of a condition subsequent, depends upon a construction of the condition, a reasonable construction to be given in favor of the beneficiary and a strict construction against a forfeiture, ...
275 Pa. at 130, 118 A. at 647. To interpret the phrase in question to mean exclusive and continuous would require a strict construction working a forfeiture of Goldie’s interest in the decedent’s estate and would not give Goldie the benefit of the reasonable construction to which she is entitled to avoid such forfeiture.
Furthermore, it is well-established that a court construing a will should do so “in [accord] with the principle which resolves doubts in favor of a widow who accepts the provisions of a will in lieu of her rights under the intestate laws.” Tarter’s Estate, 291 Pa. 458, 462, 140 A. 502, 504 (1928).
Order of the Orphans’ Court affirmed.
JOHNSON, J., filed a dissenting opinion.. We refer to decedent’s widow as “Goldie" with all due respect, because of the issue involved in this case.
. Under Paragraph 2, subsection (b) of the probated Will, upon the termination of the trust in question, the undisposed principal and income is to be distributed in three equal shares: the first share to the appellant, the second share to the decedent’s second adopted daughter Maxine, and the third share to the children of both daughters.
. In her objections, appellant also claimed that there were accounting errors in the account. The accounting objections were later withdrawn.
. Appellant argues that under common-law principles, a married woman adopts the surname of her husband unless she uses her premarital surname exclusively and continuously. Appellant cites several cases from other jurisdictions in support of this position. However, because we are dealing with testimentary interpretation, we must follow the well established mandate that the testator's intention is polestar in the construction of every will and must prevail, Houston’s Estate, 414 Pa. 579, 201 A.2d 592 (1964), and determine the effect which the testator intended through the use of the phrase in question.
. By Codicil to the probated Will, dated October 30, 1965, the testator appointed his wife Goldie the sole executrix, altering the provision in the Will which appointed appellant’s husband and the testator’s son-in-law, Gerald Freiman, and Goldie, joint executors of the Will. This is a further indication of growing trust and devotion in the Schwarzbarth marriage.
