I am trying to help sort out who Thomas Burr Kittle's parents were. I am interested into why you think it might be Hezekiah Kittle? It's very possible that he (Thomas Burr) and my great great grandfather (George W.) were brothers but I cannot say for sure.
As for Susanna Nancy Kittle, this is another mystery. I have no idea who her parents were.
Anything you have on Thomas Burr Kittle, such as census records, should help some but the main problem is that the census records don't seem to help much and there is speculation as to who the parents were of both Thomas Burr Kittle and George W. Kittle were. Geraldine Kittle didn't have a clue so I am at a loss as well.
