Hello cousin, I am Abraham's grandson! I have just began my own search and started at Tumbling Creek Cemetary, where Thomas Allen was the first interment. There are several legible Allen markers as well as Paynes, Waters, etc. Heck alot of the names you mentioned are still in Grassy/Tumbling area. I will e-mail you if you wish as I get info, if you like Abraham is in fair to poor health these days, but can recall most all of family tree starting with Thomas (who we think came from SC) and you might call grandma(Catherine) for a chat? They live on 64 in the Hothouse community, be warned, she gets a bit long winded, but she is of excellent health and mental facilities. She knows a lot about the area & history or how to get ahold of relatives. There is also several half siblings in the family you mentioned, some still around in Ga and up north. I would like to hear from you and get any info, maybe we can work together on this. I am Abe's son, David's oldest offspring and live in Ga but may be moving back to Tn soon. (Looking @ home to buy now) I really wish to spend more time with my Grandfather and work on this history.
