Fanny Walter was a member of the family at Berengrove House, and lived from 1839 until 1929. The other attachment is a family tree for the family i have put together with only one of the final generation marrying, and the daughter in question not having any children of her own. This tree is slightly out of date, as I have since established that Betsey Taylor was the mother of Elizabeth Walter.
