In the same year died Sir William Penn, in perfect harmony with his son, toward whom he in the end felt the most cordial regard and esteem, and to whom he bequeathed an estate computed at L1,500 a year--a large sum in that age. Toward the end of the year he was again imprisoned in Newgate for six months, the statutable penalty for refusing to take the oath of allegiance, which was maliciously tendered to him by a magistrate. This appears to have been the last absolute persecution for religion's sake which he endured. Though his poor brethren continued to suffer imprisonment in the stocks, fines, and whipping, as the penalty of their peaceable meetings for divine worship, the wealthy proprietor, though he travelled largely, both in England and abroad, and labored both in writing and in preaching, as the missionary of his sect, both escaped injury, and acquired reputation and esteem by his self-devotion. To the favor of the king and the Duke of York he had a hereditary claim, which appears always to have been cheerfully acknowledged; and an instance of the rising consideration in which he was held appears in his being admitted to plead, before a committee of the House of Commons, the request of the Quakers that their solemn affirmation should be admitted in the place of an oath. Penn married in 1672, and took up his abode at Rickmansworth, in Hertfordshire. In 1677 we find him removed to Worminghurst, in Sussex, which long continued to be his place of residence. His first engagement in the plantation of America was in 1676, in consequence of being chosen arbitrator in a dispute between two quakers who had become jointly concerned in the colony of New Jersey. In these transactions he had the opportunity of contemplating the glorious results which might be hoped for from a colony founded with no interested views, but on the principles of universal peace, toleration, and liberty; and he felt an earnest desire to be the instrument in so great a work, more especially as it held out a prospect of deliverance to his persecuted Quaker brethren in England, by giving them a free and happy asylum in a foreign land. Circumstances favored his wish. The crown was indebted to him L16,000 for money advanced by the late admiral for the naval service. Accordingly, Penn received, in 1681, a grant by charter of that extensive province, named Pennsylvania by Charles himself, in honor of the admiral.
