Re: Robert Alexander m.1816 IN

Robert ALEXANDER and Elizabeth CRIST were married 25 Apr 1816 in Franklin Co., Indiana.He appears on the 1820 census in Bath Twp., Franklin Co.I am researching James ALEXANDER who first appears in Franklin Co. records on the 1820 census.Later research shows James was born in PA.I have done extensive research on the ALEXANDER name in Franklin Co. but have not found my James' parents.I can link him to William, Joseph, and Elizabeth as possible siblings.I do not know anymore about Robert.If you find Roberts' parents or anything linking him to my James, please advise.
