I think Mary Starr's parents might be John Starr (b.1713 at New Garden, Chester Co., PA) and Mary Eldridge. That John Starr was son of James Starr of Chester County Starr's (Irish Quakers) and Rachel June Laybourne.

"John MAULSBY of Pipe Creek in Frederick Co., Maryland, son of David and Mary
MAULSBY and Mary STARR of same co., dau of John and Mary STARR dec'd, 21st day

Were John and Mary STARR the same as John Starr and Mary ELDRIDGE who were
married 3 Mar 1744, East Clan Meeting?
