Thank you everyone for your replies-in order- I haven't got her marriage certificate, suzard -maybe I should send for it -a father's name would be helpful. The first census I have found was after her marriage in 1851. The nearest I have found in 1841 is Sophia Holford born abt 1819 in Sussex Brighthelmsone. While the age would fit -given the "rounding" of ages in 1841 and the born in Sussex is a tick box for born in county so may be wrong-there is no evidence to place her there-and no other family members with her so no clues.
The Halford link in Chertsey is helpful Rosie-they could be members of her family-possibly her parents?
Iv'e followed the other links and it doesn't look as if the Addlestone /Chertsey baptismal records are available before 1838, sadly. It looks as though buying the marriage certificate is my best bet.
Thanks again
