Abbott is my husband's family, but I don't recall finding any of his family in this Acworth/Cobb Co. area of GA. Most of his Abbotts were in the middle GA area around Pike and Lamar Counties. The farthest that I have been able to trace those Abbotts was back to around 1802 in Jackson County, GA. From there, they went to Pike Co. and have been in that area ever since.
As for the old Campbell Co., GA area...I have some of my family who were in those parts. Some of my lines in Campbell Co. were Oliver, Huff, Robbins, Baker and Fain. There was a Lavancy Fain who married Thomas Wood. Their daughter, Mary, married W. H. Abbott. I believe that they were in that same general area because I had always heard the name of Mary and W. H.'s son, Fain Abbott, while I was growing up in the Ben Hill area of SW Atlanta which had been in Campbell Co. at one time. I suppose that there is a chance that those Abbotts could be related to yours. I'm afraid that I don't have any further information on these Abbotts, though.
