Re: Roger PURBRICK
Sorry this is so long after your post but only recently found all of this out.
Roger Purbrick married Jane Clark. They had Thomas and 8 other children. Thomas also married a Jane surname unknown.
They had Henry and 7 other children.
Henry married Sarah surname unknown and they had Harry, Millicent, George, Esther, Lucy and Ethel.
Hope this helps.
Also Roger and the Purbricks were well known in Broadwell/Filkins back in the 1700's.
Look at Broadwell history on the web.
Also Maurice Knight an American has a write up about the Purbricks from that area on his website.
