This is a suit in equity in which the petitioners, who are trustees under the will of James M. Fair-field, late of Boston, deceased, seek instructions as to the proper disposition of that share of the income of the trust estate to which Agenora D. Fairfield, now deceased, was entitled during her life under the terms of the will.
The will of the testator is composed of the will itself and five codicils. These instruments were allowed, but were to be executed in accordance with an agreement of compromise the terms of which, so far as appears, do not affect the question now presented for determination.
The sixth, seventh and eighth clauses of the will read as follows: "Sixth. After the payment of the beforementioned debts and legacies, I give the net income of my estate to be divided equally, one seventh part to each, between Agenora De Fairfield, Samuel M. Fairfield, William Fair-field, Anna Maria Fairfield, (and if she shall have any child or children, the one-seventh part of said net income shall be equally divided between her and her child or children, share and share alike) Helen Florence Fairfield, James Albert Fairfield and Dorothy Wiggin (who now lives with me and for whom I have been appointed guardian, who is commonly called Dorothy Fairfield). And the one-seventh part of said net income is given to said Dorothy, upon the express condition that said executors and trustees shall have the custody and control of said Dorothy, free from the interference and control of her father or mother, and that said executors and trustees shall expend said one-seventh part of said net income for the care, support and education of said Dorothy. And I direct said executors and trustees not to use said net income, or any part thereof, for the benefit of said Dorothy, if she shall be taken away from their care and control. Whenever any of the persons named in this clause of my will shall die, leaving a child or children, I' give the net income due and coming to such deceased person, to such child or children, and I direct said executors and trustees to pay the same to such child or children until such time as said estate shall be conveyed as provided in the eighth clause of this will. Seventh. After *451the death of said Samuel M. Fairfield, if his wife shall survive him, I direct said executors and trustees to pay to her the sum of three hundred dollars a year, payable monthly, during her life. Eighth. After the death of Agenora De Fairfield, Samuel M. Fairfield, William Fairfield, Anna Maria Fairfield, Helen Florence Fairfield, James Albert Fairfield, and Dorothy Wiggin, otherwise called Dorothy Fairfield, my said estate is to be conveyed by my said trustees to the children of the persons named in this clause of my will, each child to receive an equal share. And I hereby give my said trustees full power and authority to make such conveyance.”
By the first codicil, the testator’s son William having deceased, the testator revoked the sixth clause of his will and substituted in place thereof a new sixth clause. The only changes of importance made in the new sixth clause were that the testator struck from the list of persons named to have the income in the original sixth clause of the will the name of his son William, who had deceased, and provided that the income payable to James should be held in trust, with discretion in the trustees to pay it to, or withhold it from, him and, in certain circumstances, to divide it equally among the remaining named persons.
By the second codicil the testator revoked the gift of one sixth of the income from the trust to his son James and instead gave him “Five Dollars, in full for all I give him of my estate,” and eliminated from the provisions of the first codicil the name of his son Samuel, who had died.
By the fourth codicil the testator revoked the provision in the second codicil of his will whereby he gave James $5 and instead gave to him $10,000 “in full for all . . . [he gave] him as his share” of the testator’s estate. The second and third clauses of this codicil are as follows: “Second. Anna Maria Fairfield named in my said last will and so named in the first codicil to said will, and named Anna Maria Fitzpatrick, being the same person, having died since the making of said last will and codicils, leaving two children, namely, Boscoe William Fitts Fairfield and Fernald Churchill *452Fitts Fairfield, and I having adopted said children, I now provide as follows: Third. After the payment of my just debts and legacies, I give the net income of my estate to be equally divided, one fifth part to each, between Agenora De Fairfield, Helen Florence Fairfield, Dorothy Fairfield, Roscoe William Fitts Fairfield, and Fernald Churchill Fitts Fairfield. All parts and provisions of said will and codicils inconsistent herewith are hereby revoked; all other parts are hereby ratified and confirmed.”
Agenora D. Fairfield died testate on or about March 27, 1938. Her will was allowed in the “Superior Court of the State of California in and for the County of Los Angeles.” She left no issue. The judge entered a decree wherein he found that the share of the income to which Agenora was entitled until her death should thereafter be paid to the heirs at law of the testator, and directed that it be paid to the following named persons in the proportions specified. “ (1) One-sixth of that share to Helen Fairfield Luening of Rutherford, New Jersey; (2) One-sixth of that share to Dorothy Fairfield Miller of Dunedin, Florida; (3) One-sixth of that share to Roscoe William Fitts Fairfield of Syracuse, New York; (4) One-sixth of that share to Fernald Churchill Fitts Fairfield of Westerly, Rhode Island; (5) One-sixth of that share to James Albert Fairfield of Englewood, New Jersey; (6) One-twelfth of that share to Grace E. Demaries of Lowell, Massachusetts, a child of Etta J. Irwin, deceased; and (7) One-twelfth of that share to Raymond Irwin of Lowell, Massachusetts, a child of Etta J. Irwin, deceased.”
The only respondent who appealed from this decree is the executor of the will of Agenora. He contends that the share of income to which she was entitled during her life is payable to her personal representative until the termination of the trust. The respondent Roscoe W. F. Fairfield argues that this share of the income is payable to the four surviving named persons in equal shares. The respondent James A. Fairfield contends that it must be treated as intestate property.
The contention of the executor of the will of Agenora *453cannot be sustained. The explicit declaration of the testator that whenever any of the persons named should die leaving a child or children the net income “due and coming” to such deceased person should be paid to such child or children until the termination of the trust, manifests an intention on his part not to give anything to those claiming under any of the persons named except as expressly provided. Dove v. Johnson, 141 Mass. 287. Meserve v. Haak, 191 Mass. 220, 222. Pratt v. Condon, 239 Mass. 167, 172. This construction is not forbidden although the vesting of title to the income is not in terms limited to the lives of the persons named. Springfield Safe Deposit & Trust Co. v. Dunn, 243 Mass. 7, 9, and cases cited. It is so limited by implication.
That it was the purpose of the testator to restrict the payment of income to the respective lives of the persons designated by name to take, is further evidenced by the codicils executed by him upon the deaths of certain of them wherein he struck their names from the provisions of the trust ■— in the case of Anna Maria, making her two children whom he had adopted sharers on an equal basis with the then three surviving named persons, and whereunder the respondent James A. Fairfield was ultimately excluded from sharing in the income of the trust fund and instead was given a lump sum “in full for all . . . [the testator gave] him of . . . [his] estate.” The present case is distinguishable from cases cited by the executor of the will of Agenora, where there was no express or implied limitation of the gifts of income to the lives of the beneficiaries, as for example in Stanwood v. Stanwood, 179 Mass. 223. See also Flye v. Jones, 283 Mass. 136, 139, 140, and cases cited.
We are of opinion that upon the death of Agenora the share of income in question did not pass to her estate.
With respect to the contention of the respondent Roscoe W. F. Fairfield that the share of income involved became payable after the death of Agenora to the other persons named in equal shares, it is the general rule that “where there is a gift by will of a fund or residue to several legatees who are named, to be divided among them in equal shares, *454the gift is to them as individuals and not as a class.” Hobbs v. Chesley, 251 Mass. 155, 157. Frost v. Courtis, 167 Mass. 251. Worcester Trust Co. v. Turner, 210 Mass. 115. Flye v. Jones, 283 Mass. 136, 138. This is true even though the named individuals do in fact constitute a class and are described as a class. Boston Safe Deposit & Trust Co. v. Reed, 229 Mass. 267. Cotter v. Cotter, 293 Mass. 500. The rule also applies to gifts of income to named individuals. Stanwood v. Stanwood, 179 Mass. 223. Loomis v. Gorham, 186 Mass. 444. Forbes v. Brigham, 232 Mass. 177. Boynton v. Boynton, 266 Mass. 454. Thompson v. Martin, 281 Mass. 41. Nevertheless, it is established that the fundamental rule for the construction of wills is to ascertain the intention of the testator from the whole instrument, attributing due weight to all its language, considered in the light of the circumstances known to him at the time of its execution and to give effect to that intent unless some positive rule of law forbids. Ware v. Minot, 202 Mass. 512, 516. State Street Trust Co. v. White, 305 Mass. 547, 551.
It is also settled that, if a reading of the whole will produces a conviction that the testator must necessarily have intended an interest to be given which is not bequeathed or devised by express or formal words, the court must supply the defect by implication and so mould the language of the testator as to carry into effect as far as possible the intention which it is of opinion that he has sufficiently declared. Metcalf v. First Parish in Framingham, 128 Mass. 370, 374. Boston Safe Deposit & Trust Co. v. Coffin, 152 Mass. 95, 100. Sanger v. Bourke, 209 Mass. 481, 486. Lamb v. Jordan, 233 Mass. 335, 340. But if “There is nothing in the will that makes it certain what the testator desired to do in the contingency that has arisen” the rule just referred to does not apply. Bailey v. Bailey, 236 Mass. 244, 247. Child v. Child, 185 Mass. 376, 378, 379. Loring v. Dexter, 256 Mass. 273, 278.
A reading of the several instruments constituting the ultimate testamentary dispositions of the testator and a consideration of the circumstances in the light of which they *455were executed convinces us that it was his fixed purpose that none but those named, or in the event of their death their children, should enjoy the income from the trust estate in question. The testator clearly intended that the trust estate was to be kept intact until the death of the last survivor of the persons designated by name to participate in the income therefrom. It was a trust of the residue of his estate, and where one makes a will it is presumed that he intends to dispose of all his property and leave no intestate estate. Bates v. Kingsley, 215 Mass. 62, 63. Hedge v. State Street Trust Co. 251 Mass. 410, 412. Lyman v. Sohier, 266 Mass. 4, 8. Daley v. Daley, 300 Mass. 17, 23. On the whole we are of opinion that the testator was thinking of those designated to take the income from the trust estate as a class though not described by him as such nor shown by the record to constitute in fact a class. See Boston Safe Deposit & Trust Co. v. Reed, 229 Mass. 267, 271; Boynton v. Boynton, 266 Mass. 454, 460; Cotter v. Cotter, 293 Mass. 500, 502. (In passing, however, it may not be inappropriate to observe that it appears by express statements or inferences in the briefs of all the respondents who have argued before us that the persons ultimately designated by name to share in the income were in fact a class consisting of adopted children of the testator.)
The provision that the child or children of those named to share in the income from the trust estate, who should have deceased, shall take the “income due and coming to such deceased person” raises no difficulty, but simply makes a subclass of such child or children and puts them in place of their respective, named parents. If this provision has any effect it is to show that it is assumed that the share would go over but for such provision. The words “one fifth part to each” do not affect the question. They simply determine the proportions in which the income is to be divided. It is true that the event which has happened is not specifically provided for, but, upon our interpretation, it was not necessary to provide for it specifically. Dove v. Johnson, 141 Mass. 287, 290-291.
We think that the testator in the present case did not *456intend that any part of his estate should pass as intestate property, and that upon the death of Agenora the entire income from the trust estate became payable in equal shares to the four surviving persons designated by the testator by name to share therein. See Sanger v. Bourke, 209 Mass. 481.
' Accordingly, the decree entered in the Probate Court is reversed and instead a decree is to be entered that the income from the' trust estate is payable to Helen Florence Luening, Dorothy Fairfield, Roscoe William Fitts Fairfield and Fernald Churchill Fitts Fairfield in equal shares. Costs and expenses of this appeal may be allowed in. the discretion of the Probate Court.
Ordered accordingly.
