I can’t work out where the family are in the 1851 to trace his mum , although there is a Thomas Jones Davies HO107/2473 mine wasn’t born then and the dads name is John not David.
Any help would be appreciated

as I have only been doing this for about six months, and I am really stuck with this re-marriage.
