Thanks again, Ruskie and Ambly. I think one added element of confusion is that the mother and daughter have the same forename. There is no problem in the case of the daughter, Mary Ann Jeans. She was born on 5 Nov, 1839 in Steeple Claydon, Bucks. The certificate shows her father, George, was a carman. She then appears on the 1861 as a servant in London. In 1862 she married Francis Forester and appeared on the later censuses as Mary Ann Forrester. The problem is finding out more about the father, George jeans, and the mother Mary Ann Jeans (nee Hutchings). Probably the most reliable piece of information about them is the London Marriage and banns, 1754-1921 record. The marriage took place in Marylebone in 1837. It doesn't give the ages of George and Mary Ann but does mention she is a minor. The parents aren't present. If we assume they were roughly 21 and 17, respectively, there birth dates would be c1816 (William) and c1820(Mary Ann). After this it gets very fuzzy, as you both know. The combination of George and Mary Ann keep popping up in different places on the censuses. The ages are about right but the birth places vary (possible errors by enumerator?). Maybe george was born in Dorset and Mary Ann Hutchin(g)s in Staffordshire? Any further thoughts would be greatly appreciated. David
