William Penn was descended from an old English family which, as early as the beginning of the fifteenth century, had settled in the county of Buckinghamshire in the southern part of England, and of which a branch seems later to have moved to the neighboring county of Wiltshire, for in a church in the town of Mintye there is a tablet recording the death of a William Penn in 1591. It was a grandson and namesake of this William Penn, and the father of our hero, however, who first made the family name distinguished. Brought up as a sailor by his father, the captain of a merchantman, with whom he visited not only the principal ports of Spain and Portugal, but also the distant shores of Asia Minor, he afterward entered the service of the government and so distinguished himself that in his twentieth year he was made a captain in the royal navy. In 1643 he married Margaret Jasper, the clever and beautiful daughter of a Rotterdam merchant, and from this time his sole ambition was to make a name for himself and elevate his family to a rank they had not hitherto enjoyed. In this he succeeded, partly by policy, but also unquestionably by natural ability; for although the name of Penn is scarcely enrolled among England’s greatest naval heroes, yet at the early age of twenty-three he had been made a rear-admiral, and two years later was advanced to the rank of vice-admiral—this too at a time when advancement in the English navy could only be obtained by real merit and valuable service. Penn’s father was also shrewd enough to take advantage of circumstances and turn them to his profit. Although at heart a royalist, he did not scruple to go over to the revolutionists when it became evident that the monarchy must succumb to the power of the justly incensed people and Parliament; and when the head of Charles the First had fallen under the executioner’s axe and Oliver Cromwell had seized the reins of government, Admiral Penn was prompt to offer his homage. Cromwell on his part may have had some justifiable doubts as to the sincerity of this allegiance, but knowing Penn to be an ambitious man of the world, he felt reasonably sure of winning him over completely to the side of the Commonwealth by consulting his interests. He had need of such men just then, for the alliance between England and Holland, which he was endeavoring to bring about, had just been frustrated by the passage by Parliament of the Navigation Act of 1651, requiring that foreign merchandise should be brought to England on English vessels only. This was a direct blow at the flourishing trade hitherto carried on by the Dutch with English ports, and a war with Holland was inevitable. As this must of necessity be a naval war, Cromwell was quite ready to accept the services of so able and experienced an officer as William Penn. The young admiral fully justified the Protector’s confidence, for it was largely owing to his valor that the war, during which ten great naval
