The maiden name of the mother of Lydia Jane (Lewis) Ferguson is given on her death certificate (viewable at Ancestry.com; see weblink below). Online trees say that her mother's maiden name was Brust, but it looks more like Brush to me. The last letter doesn't look like the other "t"s, which had a long crossing line to the right of the "t". I think it looks more like an "h". Any opinions on this?
