... EVAN MORGAN, son of David Morgan, friend of Washington, and friend and neighbor of Benjamin Franklin, was born in Wales, emigrated with his father and at least one brother to Pennsylvania, about 1717. He became a wealthy merchant of Philadelphia. Evan Morgan married Joanna Biles, daughter of George Biles and Martha Blackshaw of Bucks Coiunty, Pa., in 1724. Her grandfather William Biles came to America in 1679, on the ship "Elizabeth and Sarah," and Randall Blackshaw, father of Martha, came on the ship "Submission" in 1682. The latter held some 1,500 acres of the five thousand acres puchased of William Penn by James Harrison. His father was Captain Randall Blackshaw, of Hollongee, in Cheshire, England, an officer in the army of Charles during the Great Rebellion.
Joanna (Biles) Morgan died in childbirth in 1743, at Philadelphia. She and Evan Morgan had nine children. When Evan died in 1748, he left his children well provided for...his property was considerable, aside from his business and his iron interst, and the profits from these latter were invested for the benefit of his sons until they should come of age. ..
