Just a couple of little tidbits.
There was an "Andrew Helton" that I have come across, that as I recall was a Creek (Muscogee) Chief and lived in North Alabama.
When I was researching my Helton ancestry there was "and still is" a lot of confusion as to which late 18th early 19th century Abraham Helton was the progenitor of my family. There are about four (4) of them in East Tennessee and North Georgia at the time. One of the candidates, was an Abraham Helton who was in Lumpkin, GA in 1830. We do not "believe" he is OUR Abra(ha)m Helton, but we did find something of interest in "The Georgia Black Book", which is a listing of people who attempted to obtain land in North Georgia during the early 1830's Georgia Land Lotteries. An Abraham Helton was rejected as he "is not white". Of course I've got a bunch of Indians in my ancestry, so this could have identified him as Native-American, but it could reveal some other ethnicity, as well.
Don't know if this information "rings any bells" for you, but I thought these references are interesting regarding Helton families in the Old South.
