You're welcome, parkershores.
Last night I came across an interesting piece to the puzzle, a Union draft registration from Kentucky in 1863 that shows a G. W. Wyatt in Graves County that was born in Georgia and was married:http://search.ancestry.com/cgi-bin/sse.dll?ti=0&indiv=tr...
The age was incorrectly transcribed to the computer record, but is 27 in the original record.
We find a G. W. Wyatt married to a Sarah in Graves County on the 1860 Census:http://search.ancestry.com/cgi-bin/sse.dll?db=1860usfedcenan...
I can't find when and where they married. Sarah was apparently a widow, years older than George, who came with children. The Censuses of 1840 and 1850 do not pick up any Wyatt's in Gilmer County Georgia, but maybe they escaped enumeration.
Is the Gilmer County info just a family tradition, or do you have some evidence to back it up. Anything else about wife Sarah that you can add?
Hope this helps.
