I am only working on Miles that married Plummers in Maryland. Mostly the 1700s.
The only other Miles I have come across (so far) is a Sarah Miles born 12-07-1705 Anne Arundel County, MD
She died 10-03-1788 in New Market, FREDERICK County, MD. Sarah Miles married Samuel Plummer in Anne Arundel Co. MD 1-04-1723.
Samuel lived from Feb. 9, 1691 to Dec. 12, 1759 mostly in Prince George's County, MD. IF Sarah his wife died in FREDERICK Co, MD in 1788, she must have gone there after Samuel died,to be with some of her family... I am only guessing..
Maybe that would help you somehow.
Are you looking for a particular MILES? I will try to help you if you give me a name and dates if possible.
