Hi, Don. Not sure about William, born 1770 in Oxted, Surrey.
Like Wayne, I have baptism 14 May 1769, William, s of Isac and Sarah Outram in Limpsfield (Sarah's maiden name was Bignall). I also have a burial record for him 8 Apr 1810, Limpsfield, Surrey, aged 40.
Were there 2 different Williams or are they the same person?
