The Penns were an old family in the early part of the 16th century. Admiral was the son of Giles Penn and grandson of Wm. Penn, who died 1591. He sailed with his father until the duty of every grade of seamanship was familiar to him. He entered the Royal Navy, and was at once selected for a post of command. He was a captain before he reached the age of twenty, at twenty-three, he was made rear-admiral, at twnety-five, vice-admiral in the Irish sea, and at twenty nine, vice-admiral of the Straits. He was the father of Wm. Penn, the founder of the city of Philadelphia. He died September 16th, 1670, and was buried in the parish church in the town of Bristol. [P. 9.]
