I am seeking information about DAVID THOMAS whose death is listed in Philadelphia County in a will signed June 29, 1717, proved August 6, 1718. The will names wife Mary and children: Thomas, Richard David, Samson David, John David, Catherine, Anne (Evans), Gwen and Mary. Witnesses are Griffith and William Jones. The sons and descendants of David Thomas took the surname DAVID/DAVIS. Early records place this family in Chester County. Thanks for any help. Natalie ndburrows@verizon.net
