While researching my branch of the Cantey line descended from Teague Cantey, I came across your posting. Sorry to say I don't have any information about your branch, but did notice the name Jasper Newton Cantey in another posting. Mr. Carlton Hunter wrote:
"My Canty or Cantey family is in SC. I don't know where they orginated from. Jasper Newton Canty was my great great grandfather born in 1851. Does that sound familiar?"
His posting is listed as something similar to RE: Cantey frm SC
Good luck and happy hunting!
