Morgan Co. marriage records list marriage of John T. Brown to Polly Carr on 13 Feb 1825, and to Caty Crose on 6 May 1833.

This John Brown is probably a brother of my 5G grandfather James Brown, but I have no proof. The circumstantial evidence is that they were living next door to each other in the 1850 census, which for men who share a surname is often indicative of splitting property inherited from a parent.
