Here is the will from the Weedon case:

Second; I give and bequeath to my beloved wife, Anna Plaxico Weedon all of my property both real, personal and mixed during her natural life and upon her death to her children, ifshe has any, and in the event she dies without issue then at the death ofmy wife Anna Plaxico Weedon I give, bequeath and devise all of my property to my grandchildren, each grandchild sharing equally with the other.

Third; In this will I have not provided for my daughters, Mrs. Florence Baker and Mrs. Delette WeedonJones, the reason is, I have given them their share ofmy property and they have not looked after and tared for me,in the latter part ofmy life.
