I am a Pitts researcher, but I have a note that Charles Pitt/s married first a Katherine Hunnicutt about 1713 and that she was the mother of his children, Joseph b. c1700, Milea, and one or two other girls. Charles later married Sarah Ann Hardy who most are giving credit of motherhood. Most of the dates I have and that others have are purely guesswork, except the information about Charles' death. I do have a record of his death in 1750 in Surry Co., VA. I saw there are no Pitt/s listed on your postings; however, I thought I'd ask anyway. I did have a link where I got the information but when I used it, I received info that they were unable to locate the site. I would appreciate you looking at your Hunnicutt research and see if you come up with anything about such a marriage.
By the way, my elder niece married a David (Doodle) Hunnicutt and they live in Newberry Co., SC
