Hi, Thomas -You may already have found this information in seeking out your Catherine Abbott. I think her parents are:
James Abbott, b 15 Jan 1776 NC, died 24 July 1867 Liberty Mills, Wabash Co IN Catherine Tillman, b Apr 1783 or 17 Feb 1785 Montgomery Co VA, died 24 Jan 1865 Wabash Co IN. James and Catherine were married 14 Oct 1800 in Knox Co Tenn. In 1803 James, Catherine, her parents and other Tillmans went to Preble Co OH. James and Catharine farmed and had 12 kids. In 1834 James and Catharine and some but not all of their kids/families (and maybe a few of the Tillmans) went to Wabash Co IN and settled around Liberty Mills. They were almost the first settlers there.
Catherine Tillman's parents were Tobias Tillman 1751-1845 and Catherine Sharp 1761-1837.
The Tillman family is very well documented on the internet. James Abbott's parents, however, have been a brick wall for all Abbott researchers I've been in contact with.
Your 1999 posting is so old that by now you have probably learned a great deal about your Catherine Abbott. James Abbott is my gr gr gf, and my line is thru his son Reuben. I am happy to share info and would be interested to know if you've found out anything concrete about James' life before he married Catherine Tillman.
