In the past few days I've become involved in a hitherto unknown Facebook group dedicated to the Toy family, which is the surname of my paternal grandmother. It's run by Darryl Toy who lives in Wiltshire. It turns out that while reading my entries on WikiTree he discovered that he's related to both my paternal grandparents!
Small world indeed.
I've put him in contact with George Judd, the Judd family genealogist who also lives in Wiltshire and they got on like a house on fire.
Through this group I have already discovered a 10th cousin and an eighth cousin once removed, both proven with paperwork. Now that's really stretching the tree, isn't it.
