Can you find out from your cousins where they think your mother's family MIGHT have come from. I'm chasing Actons across the North West of England and there was a vast family of them, I can tell you. I can trace the descendents of a handful, and know that we had a William (Bill) in my Great Grandmother Ellen Acton's immediate family (he was her younger brother) but I don't know what happenedto many of the siblings/children/cousins of this family. What I do know is that they were a rootless bunch, especially around the end of the 1800's and early 1900's. Reports in my own family talk of Ellen (My dad's grandmother) as having "lived under hedges". As yet I have no idea who my grandad's father was, since that is also the subject of great speculation on behalf of my family.
If you can trace your mother's people back to the North of England, with any names, then get in touch. We may have information that benefits us both.
