I believe that I have found a connection with your John Rayfield and My G.G.G. Grandfather they were brothers!!! Charles Rayfield was born in 1817 E.Malling he married Margaretin approx 1840 they had 10 children. Your relative John was born after him on the 2 Aug 1818 E.Malling he married Pricilla born 1817 in Ford. Is this correct? If so I have heaps more names from the family and our history from there on to myself. Hope this is so.
