This message is mostly intended for David Goodwin who posted here as recently as 2007. I've tried to reach him via a private email, but the email address he used here failed.
In various messages, David stated he descends from Crawford Goodwin of SC, TN, and MS. He suggested (and I strongly agree) that Crawford likely had a brother John and may have been a son of George Goodwin of pre-1800 SC.
Through y-DNA testing, there's now a potential for proving or disproving that hypothesis. Let me explain.
George Goodwin of Greenville County in a deed dated June 1789 deeded land in Union District, SC to "his children John and Josiah Goodwin." The land had been patented to George Goodwin in 1772, before the American Revolution. George's son John Goodwin may be identical to the John Goodwin listed next to Crawford Goodwin later in Pendleton District, SC.
The other gift-deeded son Josiah Goodwin married and moved to NC; he and his wife sold the gift-deeded SC land in 1799, and helpfully identified themselves then as residents of Wilkes Co., NC. A male descendant of this Josiah Goodwin has now been tested for y-DNA; the results can be compared at ysearch.org under the user ID 3865Y.
The tested male descendant has an extremely strong paper trail from privately held family records, tying the descendant back to James H. Goodwin (b. 1800 or 1802 Wilkes Co., NC) and quite powerful traditional genealogical proof that the said James H. Goodwin was son of Josiah and Lois/Louisa Goodwin of Wilkes Co., NC.
If David or his father, brother, paternal uncle, or son were tested and the yDNA shows a match tothis descendant of Josiah, that data would go a long way to confirming that Crawford Goodwin was another son of the George Goodwin who lived in Union, Greenville, and Pendleton Districts of SC.
Also, while searching for another surname, I recently found proof that Crawford Goodwin served in the American Revolution, per his 1833 testimony from Perry Co., TN for Captain William Young's pension. In the affidavit, Goodwin swore he'd served two tours of duty under Thomas Brandon. The Goodwin surname was mistranscribed previously as Gorden, but can be seen as Goodwin at image 14 in the fold3.com scan of the William Young S4742 pension. Service under Thomas Brandon is highly suggestive of a connection to George Goodwin, since Brandon's blockhouse was on Fair Forest Creek in Union District. The land George deeded to his sons was also in the Fair Forest Creek drainage in Union District.
