From the "Marriage Records of Highland County, Ohio (1805-1880)" by David and Jane McBride (1962):
TRUETT Elijah m. Eliza Jane TAYLOR 23 Nov 1841 by David Reed, M.G.
Joseph m. Jane ELLWOOD 29 Apr 1812 by Moses H. Gregg, J. P.
Eliza Jane m. Thomas J. DAY 28 Apr 1842 by David Rees, J.P.
I checked familysearch.com for Elijah. IGI file says he is son of Gilead Truett and Nancy David. Ross CO. marriages gives her names as Ann David married Gillet Truitt on 12 Jan 1815. Gilly Truitt then married Angeline Bower 7 Oct 1828.
I have some more from 1850 Census of Ross Co. E-mail me if you want it. I'm trying to figure out who Eliza Jane Taylor's parents were, but may not be able to. There were a lot of Taylor's around then.
