Isaac Allerton was an Englishman who sailed to North America on the Mayflower in 1620 with his wife, three children and an apprentice, John Hooke. Born in England in the late 1500s, he belonged to a congregation of Separatists who were not tolerated by the established church and who left for the Netherlands before emigrating to New England. In Leiden he worked as a tailor and joined other exiles preparing for a new settlement in Virginia that became Plymouth Colony.
Leiden period and the Mayflower voyage
Allerton and his family lived for several years in Leiden, in the Netherlands, where many English Separatists settled. Contemporary accounts note that he practiced a trade—historically recorded as a tailor—and took on an apprentice. Political and religious pressure in England, where his congregation’s beliefs were unwelcome, pushed the group to seek a safe harbor; they ultimately organized the transatlantic expedition that sailed on the Mayflower. Allerton was among the few who had prior experience abroad and in commerce.
Role in Plymouth Colony
In Plymouth Allerton was an influential participant in civic and economic affairs. He served in official capacities as an assistant to the colony’s leaders and took on responsibilities for procuring supplies and managing debts. His work often required travel and negotiation with merchants and investors in England on behalf of the colonists.
Business activities and disputes
Allerton became a prominent merchant and agent for the colony’s business, but his commercial activities later drew criticism. Some colonists accused him of poor accounting and putting personal trade interests ahead of communal obligations. These disputes led to strained relations with other leaders and eventually to his departure from full-time life in Plymouth.
Later life, family, and legacy
After leaving Plymouth Allerton moved within New England and continued trading. His family ties and descendants became integrated into several New England communities. Historical assessments of Allerton are mixed: he is remembered both for key services to an early English colony and for controversies over finances and private commerce.
