Isaac Penington

1616-1679. Quaker apologist. The eldest son of Sir Isaac Penington, lord mayor of London (1642-43) and a staunch Puritan. In 1654 he married Mary Springett, a widow; both had for some time been among the “Seekers,” a group eventually amenable to Quakerism, and Isaac's “convincement” took place in London, 1658. He was imprisoned six times beginning in 1661 for refusing to take the Oath of Allegiance.* Several long imprisonments in the Reading and Aylesbury jails were borne with cheerful endurance, characteristic of his innocency of life universally recognized. As a leading Friend, he was a close acquaintance of George Fox.* Five children were born to him, one son, Edward (1667-1711), emigrating to Pennsylvania. His stepdaughter, Gulielma Springett, married William Penn.*
