I actually saw your post over on the ancestry.com site and then checked to see if you posted here.I prefer this site so I am answering you here.
My grandmother, Josie Callender Shirkey, was a Henderson Co., KY native.She is the daughter of Alexander Overton Callender and Josie Cobb.
I have some Callender information from the County History, Census records, my grandmother's recollections and some other research.I have also had contact with some other Callender relatives.
I would be glad to share. Can you tell me some dates and names of as far back as you might have so that I can see what is relavent and how my info might fit.
Alexander Callender was the son of Thomas Jefferson Callender and Martha Chiles Harris.They were born around 1810.I don't think I have anything further back.I would bet you may also be descended from Thomas and Martha.
