I'm married to an Atwell, the family seem to originate in the Congresbury area of Somerset.
My husband's great grandfather Joseph Atwell moved to Newport, Monmouthshire looking for work, he got work as a coal trimmer on the docks. Most of his Atwell side of the family still live in Newport.
I,ve managed to trace back to George Atwell 1788 & Sara Cox 1789.
Anything that might be of interest to you just ask.
My 3x great grandmother was Hannah Atwell baptised in Weare in 1809, with parents' names given as Samuel & Ann. I have confirmed her father's name with her marriage certificate. I know that some of her siblings were also baptised in Weare but mother's name was Elizabeth. One of them, William married in Bristol in 1838 and was in Bedwellty, Mon. in 1861 and Ystradyfodwg, Glam. after that.
A recent discovery was that Hannah's other siblings were probably born in Nailsea. There is also a marriage there for Samuel Atwell and Elizabeth Watts in 1805. I now suspect that Elizabeth and Ann are one and the same.
There are a lot of Atwells in Nailsea and some were miners who ended up in Monmouthshire & Glamorgan. I haven't yet looked into Congresbury but it could be a link between Nailsea and Weare so thank you for the prompt.
