This line of the Dyches family begins with
Josiah Dyches and Lucinda (?), who came from South Carolina to St. Tammany Parish, Louisiana – and then to Williamson county (and other counties in) Texas.
Most researchers for this Dyches line list Lucinda’s maiden name as Taliaferro, but it has been rightly pointed out to us by someone far more knowledgeable (thank you, P.M.!) that there is no primary evidence of that. If you personally can point the way to any, it would be greatly appreciated.
