My great grandfather's (James Hamilton Carr) sister married either a Cochran or a Blair, I'm not sure which. James Hamilton Carr's father owned a plantation in the Cumberland Valley area of Tennessee, which was lost after the Civil War. Sometime after the Civil War his sister and her family moved to Texas. My great grandfather also moved to Texas. I don't know James Carr's sister's name, but am trying to locate some of her descendants. I would appreciate any information.
