Sorry - I havne't been paying attention to this thread, but I was cleaning off my desktop and noticed that I had a list of marriages of Crawfords from Floyd county, Indiana.  and one of those was to a William H. FRAVEL.  This maybe old news to you, but just in case it's not.  I don't have any other info than the below, but the New Albany, Ind library has some great people working there - you want the Indiana room. Julie Tustin, Calif MARRIAGES / Wm. H. Fravel to Elizabeth Crawford. New Albany Ledger. 10-15-1869. p 2, c 2.
