From what I can tell Lucy Matthews Brass may have been his mother-in-law. His first wife Samantha Scott-married 6 Nov 1823 and died on 4 Nov. 1824. He remarried a Mary Brass on 7 Apr. 1825 There are several family trees on ancestry.com that indicate this. They had a boat load of children. I would have to double check the ages to figure out who was who as far as there mother goes.
Hope this helps. I will also try to find nfo on Lucy matthews Brass.
