For the first time in a while I was contacted by a Gammon with ancestors from North Devon like mine. Malcom now lives in Western Australia, and sent me some brief information that he knew about his family.
I have pulled together a tree from this information and published it on my Drupal website:
Malcom’s grandfather is Stanley A GAMMON. Stanley married Ivy M PARKIN in Barnstaple in 1921 (Sep 1921, Barnstaple, Vol: 5b, Page: 1073). A copy of this marriage certificate would confirm Stanley’s parents. In any case, I should be able to find Stanley in the 1911 census.
You will notice my menu needs restructuring after adding so many trees!
Update 26.1.17: On the new GoONS website with Drupal 8, the menus look okay (although I have not checked from a mobile device). I have also added a side menu which gives access to the Family Groups via a “Place” categorisation.
