So I have managed to finish cross-checking another branch of the ROAK Family Group and managed to check back to Philip GAMMON who was born about 1782 in Bratton Fleming, Devon, England.
Whilst gathering more entries for my Baptism index from Bratton Fleming, I discovered that the early Parish Register there (from 1559-1670) went missing many years ago. So I am not sure how far back we will be able to go with this tree.
This tree includes connections to the WILL Family Group, some Australians, and some Welsh Gammons.
