I have two copies of the Geo. Bennett book, one written around l956 and another around l960.I believe there was at least another because someone gave me a page gleaned from a Bennett Book and that informtion is not on that page of the 1961 Bennett Book.
I have found a few mistakes, but also found some things I did not know.His book looks to be hand colored, typed on a typewriter and home published - actually this took lots of effort and time.Quite interesting to look at the hand colored charts and read the narrative.
The 1961 books is about two inches thick.I also have letters written to the book's owner asking for information on his family.There were letters and postcards inviting them to a National Asbill Reunion in the late fifties.Geo. Bennett sites one family from Ridge Spring, SC who went to the reunion.
