The Pennsylvania Supreme Court has held that a testator's grandchild, who was adopted after the testator's death, was entitled to share in a testamentary disposition of trust income to his daughter's children, if any, after her death. The Court allowed this distribution where it was clearly shown that the testator knew at the time he executed his will that his daughter could have no children and already had adopted one, who subsequently died.
