I've been looking for any information on my great-grandmother Ida P. Harrison b.abt.1855-56. She married my great-grandfather John R. Jarrell abt.1874-75. He was the police chief of Augusta GA in the late 1800's. I have no idea where she came from but there are the obligatory family stories that she was a descendant of William Henry Harrison. Of course they were mostly from VA and OH.
Your posting was one of the first times I saw a Harrison and Augusta together anywhere on the internet. She was from the general time frame of your query, so if her name were to "hit" in any of your searching Please keep me in mind as I have a lot of info on her descendants.
