Have you ruled out Isaac Mead Harris as John W.'s father? He came to Morrow Co. at the same time as Jonathan Askins and Reuben Harris.
I've pretty much limited myself to direct lines, unless I get stuck, then I try working through the collaterals. I'm impressed with all that you've accomplished.
So who did your 4xg grandfather John Harris marry and what year was he born? Was Jesse Harris part of this family?
Is this your family then?
http://genforum.genealogy.com/cgi-bin/pageload.cgi?knox,ohio...It's amazing how many and how prominate the Askin families were - and how many married into the Harris families; there's even a Harris-Askins House in Westerville built as a Rotary Project to provide low income housing to the elderly of central Ohio. Lots lof luck sorting all that out!
From reading your posts, it sounds like you have quite a lot tied down and documented with source records. Mary Urban had said Almira remarried a Moffit; this is her, right?
http://www.familysearch.org/Eng/search/frameset_search.asp?P...Have you ever found the records of Almira's marriage to M. Moffitt or John Harris' death record?
