Information was obtained by searching Ancestry.com with the exception of "A History of the Kiddoo Family in the United States 1780 - 1981" compiled by Bette Butcher Topp. I've seen many variations of the surname Kiddoo (e.g., Kilduo, Kildoo, Kido, Kidoo, Kiddo, Caldoe, Caldoo, Kadoo, Kiddoe, Kildoe, Kildue, Kildew, Caldow, Caddow, and Caddoo). I do not have any other information on Mingo Kiddoo. Good luck with your research.
