Mary was born about 1806, possibly to William and Lydia in Beaconsfield.
She married James Freeman Gage Spicer, the owner of a number of paper mills in Wooburn, in 1834.
She passed away in early 1871.
Surname sometimes spelt Pryce.
1851 Census says she was from Wycombe.
Marriage record includes a witness Sarah Pryce.
And there is a Price family in Beaconsfield, William and Lydia with daughters Mary (1807): https://www.findmypast.co.uk/transcript?id=GBPRS%2FBUCKINGHAMSHIRE%2FMAR%2F000100547%2F2, and Sarah (1813): https://www.findmypast.co.uk/transcript?id=R_959655834
Wooburn is just down the hill from Beaconsfield, so it fits in terms of distance, but not with Mary giving her birth location as Wycombe.
