Does anyone have any information on a Boyd family living in the Chester, Lancaster, and York County Area of Pennsylvania about 1740. I have a Frances Boyd who married William Park/Parke. William was born in Chester County s/o John Parke and grandson of Arthur Parke. He married Frances Boyd. They eventually settled in Cumberland Co and then in York Co, in Dillisburg. The DAR lists her name as Frances and children and grandchildren are named Frances. Engles has her name as Agnes. I do not find that name any other place. William and Frances are supposed to be buried at a Silverspring Cemetery. I have not been able to locate that cemetery.
Any help is greatly appreciated.

Thanks
