Sorry to be so slow in responding to you but I simply don't have the time I would like for genealogical work.
About all I can add for Catherine Rupert Bill is that my info shows she married a Clifford Harris. That is probably what you really need but when or where or who his parents were I have nothing more on. Catherine did have an older sister, Rose Minetta born 21 Sept. 1865, and a younger brother, Edward Manning born 19 Nov. 1869. More recent than that on her and her siblings I have nothing but can give you her full Bill ancestry if needed. If you descend from this woman then we both descend from Asahel Bill, who was my gr, gr, gr, gr, grandfather.
