I'm so sorry. It's been a few years since I looked at this branch of the family and I had totally forgotten the previous posting re Elizabeth.
Re Mary : I have the 1841 census info for her. She is in N. Wingfield with husband, Joseph and children Samuel, Geirge, Eliz., Joseph, Mary, William.
Husband died in 1845 and I am only now beginning to track Mary.
Apologies once again for giving you extra work
