Hello both!
I had a look for George and came up blank!
Any BAKER witnesses to the marriage Babs? In fact, who were the witnesses - they might be step-relatives or something helpful!
The possibilities are that George used a different name on earlier censuses, that he made up his father's name or MOST LIKELY that he was in the part of Monmouthshire for which the 1861 census is missing.
Which doesn't explain where he is in 1871.
Still hoping to help!
kind regards, Arranroots
