I'm trying to find my great-grandfather John Thomas Osborne who was from Norfolk, and by a process of elimination have decided he's likely to be the John Osborn who was in Downham Market Workhouse in the 1871 and 1881 Census. I think his mother was Sarah as she was also in the workhouse in 1871 and also two siblings Rebecca and Mary. By 1881 Sarah and the two girls have gone, I've traced the girls but not Sarah, and some more Osborn's have joined John - I believe only Annie was his sister. I'd be grateful for any information about who his father was, what happened to Sarah, and what happened to John when he left. I know he was in Sheffield in 1893 when he married his first wife but can't find him on the 1891 Census.
