If you go (again) to FamilySearch website, you can read the following will >
Charlotte WILD - Waimate - 1920 - widowHer will was dated 24 April
1912 and it named all of her living children.
There was also a codicil dated 6 November
1917 which sought to re-direct her earlier bequests to three of her children. (Seems to have been the result of the death of a son (or grandson ?) named Harvey and his legacy was transferred to three of Charlotte's other children).
The last of the children named in the Will of Charlotte WILD, widow of Waimate is
Mary GRAY (the wife of Robert GRAY)Am supposing then that this Mary GRAY is the daughter formerly married to VINCENT ??
[Think there may be another twist to this Mary however, but I'm still investigating that.
