Does anyone have documentation of this James McCracken's Revolutionary War service or pension records? I have a few secondary sources indicating he was in a South Carolina regiment, possibly Sumter's SC Brigade, and lists of possible campaigns and commanding officers. (Bobby Gilmer Moss lists 10 McCrackens and McCrackins in her "Roster of South Carolina Patriots" (1983), including James).
But no matter how I ask, the National Archives can't come up with any service records. I know they exist because my aunt says she corresponded with another descendent in the 1980's who had copies from the National Archives.

Can anyone give me a clue about where these records might be, so that I can try to order them again? Or perhaps my James McCracken is not the man who served at all?
James McCracken b. c. 1752 Scotland, m. Mary Smith 1779 Union Co, SC, d. 1824 probably Alabama, burial place unk., family memorial marker at McCracken-Tidwell Cemetery, Lawrence Co, Tennessee

Thanks!
