If the testator had children or other descendants and he did not know that he had children or other descendants, or he thought that they were dead, or where the children are born to the testator after his death, or where the children are born to the testator before his death, but after the will was made, the will shall be valid only to the extent of the disposable portion of the testator, in accordance with section
140.
215. Interpretation of wills.— (1) Where any doubt arises as to the interpretation of a testamentary disposition, the intention of the testator shall be gathered from the will and accordingly carried out.
(2) When the words of a will are unambiguous, but it is found from extrinsic evidence that they admit of interpretations, one only of which can have been intended by the testator, extrinsic evidence may be taken to show which of these interpretations was intended.
