became betrothed to Mary Norris in Leiden by October 7, 1611. He lived in Pieterskerkhof near St. Peter's Church. In 1614 he became a citizen of Leiden. While in Leiden in 1619 Allerton worked as a tailor; John Hooke, who would travel with Allerton on the Mayflower, was his apprentice. The Mayflower voyage The Allerton family boarded the Mayflower consisting of Allerton's wife Mary, three children and an apprentice, John Hooke. The Mayflower departed Plymouth, England on September 6/16, 1620. The small, 100-foot ship had 102 passengers and a crew of about 30–40 in extremely cramped conditions. By the second month out, the ship was being buffeted by strong westerly gales, causing the ship's timbers to be badly shaken with caulking failing to keep out sea water, and with passengers, even in their berths, lying wet and ill. This, combined with a lack of proper rations and unsanitary conditions for several months, attributed to what would be fatal for many, especially the majority of women and children. On the way there were two deaths, a crew member and a passenger, but the worst was yet to come after arriving at their destination when, in the space of several months, almost half the passengers perished in cold, harsh, unfamiliar New England winter. On November 9/19, 1620, after about three months at sea, including a month of delays in England, they spotted land, which was the Cape Cod Hook, now called Provincetown Harbor. And after several days of trying to get south to their planned destination of the Colony of Virginia, strong winter seas forced them to return to the harbor at Cape Cod hook, where they anchored on November 11/21. The Mayflower Compact was signed that day. Issac Allerton was one of the signers. Life in Plymouth Colony Of Isaac Allerton and his first wife, William Bradford recorded: "Mr. Allerton's wife died with the first, and his servant John Hooke. His son Bartle is married in England but I know not how many children he hath. His daughter Remember is married at Salem and hath three or four children living. His daughter Mary is married here and hath four children. Himself married again with the daughter of Mr. Brewster and hath one son living by her, but she is long since dead. And he is married again and hath left this place long ago." The colony government chose John Carver as
