I suspect that my g. g. Grandfather and his brother married two sisters, in about 1831. As of yet I don't know the sisters' maiden names, but hopefully that will change soon, when I get a copy of the birth certificate of one of the siblings born in 1844. Are there any other tricks or tips to find the marriages ? I think it may have been a double wedding. The brothers came from Eltham Kent, and I think the sisters came from Chipping, Nr Buntingford, Herts.
