Chris, I notice that this David is much later. Do you think he is a descendant of the first David born about 1690 and who had land in 1714 in New Munster, Cecil Co. Md?It may be that David moved to the Rock Church which early on did fall in Chester co. and was across the border with Cecil Co. Md.
Is this David Alexander your line?I have found a Rev. David Alexander who is of Pequea, Pa that is not of our line. Helen Smith
