I was wondering if anyone is researching this family? I have an Ann Risby who married Leopoldus Silvanius Albertus Diver in 1733 in Lakenheath, Suffolk, and Christopher Dullingham in 1749 in Soham, Cambridgeshire.
Ann Risby was probably born about 1714 and has a sister, Thomasin Risby, born about 1718. Their mother is Sarah, who died in 1736 in Soham, at which point she was married to an Edward Isaacson, presumably her second husband.
Sarah, Ann and Thomasin all received land from the will of a Thomas Palmer, who may be a relation.
I don't know where Ann, Thomasin or Sarah came from, or the name of their father/husband, except that his surname was presumably Risby, of course! Would love to discuss this with anyone researching the same family. Please reply here or send me a message.
