SOURCES AND BIBLIOGRAPHY


In 2019, Caleb Johnson, Sue Allan and Simon Neal published their findings on the English origins of Isaac Allerton (NEHGR 173:197-205). They demonstrate he was almost certainly the son of Bartholomew and Mary Allerton of East Bergholt, Suffolk, and belonged to the same recusant community as Mayflower passenger Elizabeth (Barker) Winslow. In 1609, he was apprenticed to London blacksmith James Glyn, but he broke out of the contract within a couple years and went to Leiden, Holland, where on 4 November 1611, when he married Mary Norris.  Isaac had a sister named Sarah who also resided in Leiden, and who married future Mayflower passenger Degory Priest.  He was probably also related, perhaps a brother, to Mayflower passenger John Allerton.

Isaac Allerton is one of the most complex figures in early Plymouth Colony.  He was elected assistant to Governor Bradford in 1621, and continued in that capacity well into the 1630s.  He was the individual sent to handle most of the buyout negotiations with the London investors that commenced in 1627, and continued through the early 1630s.  Allerton soon began to take advantage of his position by engaging in some personal trading deals, and engaging the Pilgrims' joint-stock company in business ventures they had not authorized.  After driving the colony deeper into debt with ill-advised business opportunities, he was eventually removed and replaced by Edward Winslow.  After the death of his wife Fear in 1634, he retreated to the New Haven Colony and married there to Joanna Swinnerton.  

Allerton became an active merchant trader, engaging in transactions and trade with many neighboring colonies including the Dutch at New Netherlands; New Sweden; Virginia; Massachusetts Bay; and Barbados.
