I subscribe to ancestry.com and I was searching land and probate records for William Harrison and I saw William A. Harrison in Alabama. my gggrandfather William Harrison b. 1816 m. Elizabeth Sherman 1841 in Stewart Co. Ga. d. 1889 in Ga. His son Zachariah Taylor Harrison, Sr. and Junior both were in Dale and Henry Co. Alabama. I think he may have held land in Coffe Co.,so I was doing this research and did see William A.. you could also look for some of the other names there in regards to land.
