This is very interesting, when I applied for the birth cert they sent me the one for the illegitimate Jemima, whose mother just happened to have the same name as Joseph's younger sister, so I then assumed that Joseph and Eluza had "adopted" the baby. All makes sense now as I've been puzzling all day as to why my DNA results just received are linking to members of Eliza's family! How do I go about getting the correct cert now, is there a box to fill in on GRO for mothers maiden name?
