I know my gggrandfather was William A. Alsup. His wife was Sarah Emeline Brister.I have not been able to pin down his father.The 1860 Milam Co. TX census says William was 26yrs old and born in MS. The 1850 Yalobusha Co. MS census shows a T.H. Alsup with a William of 17yrs of age but born in TN. Is this the same William of 1860 TX? Does the T. stand for Thomas, if so is his father Drury Alsup who also ended up in Texas? If anyone has any definitive info on this please respond.
