John (Jack) Duckenfield was my husband's grandfather. He was trampled by one of his horses and killed. Albert was his brother. I think Annie was his wife, but I've not ordered the marriage certificate so am reluctant to say that I am positive of the marriage...saying that, my father in law says that his aunt was named Annie.
How may I help you in figuring out the connection? This family was in Sheffield, and one branch went to Aston cum Aughton. Albert had 4 children; John (Jack), Mary, Doris and one whose name my f-i-l can't recall anymore.
