their first governor. Allerton was his assistant from 1621 to 1624, and afterwards serving on the colony civil affairs council. After the early death of John Carver in April 1621, William Bradford was elected governor in Carver's place. In 1626 Allerton became involved in the colony's finances. With the dissolving of the Merchant Adventurers there was a great need for the colonist to pay their debts. William Bradford, Allerton and others took on the colony's debt to the Merchant Adventurers with the provision that they be given a monopoly in the fur trade. Isaac Allerton traveled to London in 1626 to negotiate a new agreement with the Merchant Adventurers group which had given much money for the trip and the maintenance of the colony. In the 1627 division of cattle (equal to a census) the Allerton family is listed with wife Fear and children Bartholomew, Remember, Mary and Sarah. About 1628 a young man came to work as an apprentice under Allerton. This was Mayflower passenger Richard More, who then was about age 15 then and a world away from his parents in England. Richard had been part of a historic incident in which he and three siblings were placed aboard the Mayflower in 1620 by their putative father, Samuel More, without their mother's knowledge, after her admission of adultery. All three of Richard's siblings perished the first winter in America, and he alone survived. Richard worked under Allerton for the usual seven years, during which time he learned to be a sailor, working largely in the fishing and coastal cargo-transport business, and in Allerton's business development in Maine. By 1635, Richard was back in London, but the reason for the trip is unknown. His name appears on the manifest of the Blessing in 1635.<ref name="packrat-pro.com">Manifest of the Blessing 1635 [http://www.packrat-pro.com/ships/blessing.htm]</ref> Later, More was an Atlantic ship captain. Allerton returned from England in 1628. He made a payment to the Merchant Adventurers investment group thus reducing the colony's debt to them. The debt was still a tremendous amount of money estimated into the thousands of pounds. He had obtained a land grant at Kennebec (in present-day Maine), provided by the Council for New England. The Kennebec grant was officially authorized in January 1629, and the Plymouth colonists began to build a fortified trading structure at Cushnoc on the Kennebec River, with Edward Winslow as overseer in charge of the operation.
