DISSENTING OPINION OF
ABE, J.The trial court was called upon to decide who were to take under the will of Ho Poi as his “lawfully begotten children.” Thus, its task was to determine the testator’s intent as to who fell into the class of “lawfully begotten children.” Booth v. Baker, 10 Haw. 543 (1896); Brown v. Brown, 11 Haw. 47 (1897); Rooke v. Queen’s Hospital, 12 Haw. 375 (1900); Collins v. Hodgson, 36 Haw. 334 (1943); Knight v. Carter, 31 Haw. 535 (1930).
The majority of this court seems to engage in the following line of reasoning:
1) It is admitted that Ho Poi fathered all 17 of the children in question;
2) It has been previously decided by competent courts that the 17 were all children of Chang Shee;
5) Ho Poi and Chang. Shee were husband and wife;
*404) Therefore, the 17 are the “lawfully begotten children” of Ho Poi.
Thus it appears that this court assumes that the issue of maternity of the original 17 children admittedly fathered by Ho Poi was decided in Equity No. 5664 and affirmed in In re Estate of Ho Chang Shee, 48 Haw. 193, 397 P.2d 552 (1964). On the basis of this assumption, it holds that the appellants (the seven) are collaterally estopped from litigating the issue of whether the other ten children were of Chang Shee’s body.
The issue in Equity No. 5664 was the determination of the heirs of Chang Shee, under the intestacy statutes applicable at that time (now HRS § 532-4, which provided that “the property shall be divided equally among the intestate’s children . . . .” The court in Equity No. 5664 found that all 17 were the children of Ho Chang Shee. Therefore under the intestacy statute each took one-seventeenth of her estate. The Circuit Court never specifically decided that all 17 were borne by Ho Chang Shee.
Similarly, this court in In re Ho Chang Shee, supra, simply decided as a policy matter that under the facts of the case, the 17 were “children” of Chang Shee for the purpose of intestate succession. It stated: “we reach the same result even if it be assumed that Ho Poi fathered children by both Chang Shee [purported mother of the seven] and Chun Shee [purported mother of the ten].” 48 Haw. 193, 203. 397 P 2d 552, 557.1
*41Finding that a person is a child of a female decedent for the purpose of taking an intestate share does not necessarily mean that she bore that child. For example, an adopted child may take from adoptive parents. HRS § 578-16. See also SLH 1905, Act 83; Estate of Kamauoha, 26 Haw. 439 (1922); Trust Estate of Holt, 42 Haw. 129 (1957). Furthermore, under In re Ho Chang Shee, supra, it appears that a person admittedly fathered by a husband may take from the husband’s wife who dies intestate if that person has been treated by both as their child, absent any “irrefragable” proof to the contrary.
I believe this court in Ellis v. Crockett, 51 Haw. 45, 55, 451 P.2d 814, 822 (1969), correctly states the operational effect of collateral estoppel; it “precludes the relitigation of a fact or issue which was previously determined in a prior suit on a different claim between the same parties or their privies . . .” (emphasis added).
However, it appears to me that neither the trial court in Equity No. 5664 nor this court in In re Estate of Ho Chang Shee, supra, determined the issue of the maternity of the 17 children. Thus, I believe it is error for this court to hold that the appellants are estopped from questioning the maternity of the ten children under the doctrine of collateral estoppel.
Unless there is evidence contained in the will to the contrary, the normal meaning of words used in a testamentary instrument will be taken to indicate the testator’s intent. Spreckels v. Spreckels, 21 Haw. 556, 565-66 (1913).
*42The word “children” usually means immediate offspring. See Estate of Hartwell, 25 Haw. 213 (1916). If Ho Poi had devised his estate to his “children” there would not be any doubt that all 17 are within this class of devisees. The devise, however, was to his “lawfully begotten children.” To be lawfully begotten, a child must have been born or conceived to a husband and wife during coverture. Honolulu Investment Co. v. Rowland, 14 Haw. 271 (1902); Appeal of Edwards, 108 Pa. 283 (1885). Thus under Ho Poi’s will only his children born of Chang Shee during their marriage are “lawfully begotten children” and therefore his devisees.
The trial court refused to allow the seven to introduce evidence as to the maternity of the ten, ruling that the issue had been decided in Equity No. 5664 and in In re Ho Chang Shee. This court affirms on the same theory. Based on the reasons stated above, I would reverse and remand for further proceeding on the issue of maternity. The seven should be allowed to prove the maternity of the parties.
I, therefore, dissent.
See also 48 Haw. 193, 201-202, 397 P.2d 552, 557, where this court said:
“There is much in the situation which tends to support the allegations of ‘the seven.’ Perhaps Ho Poi did father children by both his lawful wife, Chang Shee, and another woman, Chun Shee. However, if this is admitted, the parentage of all children born after Chun Shee became of child-bearing age becomes doubtful. There is then no overriding reason to assign any of these children to Chang Shee or Chun Shee. If it is held, as ‘the seven’ maintain, that the sworn testimony of three of their number and of their mother and father and also the petitions for several certificates of Hawaiian birth were all part of a deliberate plan for the purpose of avoiding possible criminal action against Ho Poi, would not such a plan of deliberate falsification under oath also cast a cloud on the parentage of each of ‘the seven’? If Kam Kong Ho (one of ‘the seven’) and Kam Hou *41Wong (one of ‘the ten’) were actually born within 7 days of each other, as ‘the seven’ contend but ‘the ten’ deny, how does one prove that either child must necessarily have been born of either mother?
These considerations illuminate the desirability of applying a presumption in this case which places the burden upon ‘the seven’ of showing by ‘irrefragable’ proof that the relationship of mother and child did not exist between Chang Shee and each of ‘the ten.’ The judge below concluded that no such standard of proof was met. This court cannot now say that his conclusion is ‘clearly erroneous,’ even though we have reason to doubt the credibility of some of the testimony on the part of ‘the ten,’ as well as some of the testimony on the part of ‘the seven.’ ”
