Back to the Nottingham Oldhams
I still haven't been able to locate either William Henry Oldham or Thomas Oldknow Oldham in the local baptism records, although the Census records suggest they were both born in Nottingham.
The next step will be to find the non-conformist registers and see if they are in there. I know there are some at the Nottingham Archives, it's a matter of finding the right one!
A couple of years ago I was in touch with Gillian Kelly via her website here. She has done extensive research on the Nottingham lacemakers who went to Calais and then later emigrated to Australia. Although my Oldhams weren't in Calais at the time of her research (they were there later) she did manage to find a baptism in her records of a Gervase Oldham on the 25th May 1842 in the Methodist Chapel in Calais. His parents were William Oldham & Eliza Oldknow.
This does fit in with my Oldhams, and I do have a record of a Gervase born in 1842 to parents of the same name, but according to his birth certificate he was born in Beeston, Nottinghamshire on the 25th August!
Back to the records I think!
