I believe this William Willey is the brother of my GGG Grandfather Robert Willey.
and their parents are George Willey and Sarah Webb.
Several Willey decendant's arrived in Australia which including Willam and Mary Buttle's son Joseph Willey and his wife Anne House or Howes? along with his 2 cousins Alfred and Fanny Wheadon(my GG Grandparents)and Frederick and family. I also believe Robert Willey came to Australia too still trying to work this out.
Do you have messages on other message boards?
I guess you may have a lot of information on this family already no doubt.
feel free to say hello anyway.
