Yesterday, I received such a piece of information. This wasn't a document but a DNA result - a yDNA result. Apparently, my Crawford line is its own branch with my closest Crawford match being a descendant of Edward Crawford of Overton, Tennessee.
So, one of my new goals is to try and determine how this Edward Crawford might fit in with all of my James Crawford research. With only five Edwards in my database it is a relatively unusual name. Unfortunately, Alexander and Mary (McPheeters) Crawford had a son named Edward. Thus, there will be confusion in online trees as to the parents of Edward.
In looking back thru my Kentucky research notes, I do have some data placing an Edward Crawford in Madison County, Kentucky during the time period of my James Crawford research.
In 1795, Edward Crawford was listed on the tax records for Madison County, Kentucky as a male over 21 with 2 horses and 3 cattle.
