My Barnhart line seems to dead end at George Barnhart who was born sometime around or before 1782 and died between 1828 and 1834 in Greene County, GA. The property came from the land lottery which he entered as a Revolutionary war veteran. He married a womand named "Caty" and all the generations from there to me are well documented.
Anyway, I found a George and George Jr in Maryland that look like they could be the previous generation and George before moving to GA.
I am posting to see if anyone has other information to support or disprove the idea. It isn't solid enough for me to feel positive, but the pieces do fit nicely.
First, there is a record of George Barnhart joining the Revolutionary army there:
Census-Year 1790 State MARYLAND Counties Anne Arundel, Baltimore City, ..... FREDERICK Barnhart George 1 . 4 . . . BALTIMORE-CITY Barnhart Jacob 1 4 2 . ... http://www.us-census.org/pub-ftp/md/1790/index-b.txthttp://www.us-census.org/pub-ftp/md/1790/index-b.txt
23 results that don't seem relevant except one mentions a brother George to their ancestor about 1763 in MD. There is a George and a younger George who looks to have married and had a child shortly before 1800 and then seems to disappear from MD. There is a war record for a George from that location. And now comes the backward logic part - I know it is only one forum, but take off the Maryland and you get hundereds of hits on George. This set of George Barnharts appears "unclaimed". That doesn't mean you jump to the conclusion this is the George Barnhart who moved to GA, but there is no evidence to the contrary to explain away either.
