- He had been a long-time member of the Pilgrims' church in Leiden, and was recorded as having been a tailor from London.
- He married his first wife, Mary Norris in Leiden, Holland in 1611 and there had children Bartholomew, Remember and Mary, all of whom came on the Mayflower with him. He and Mary buried a child not yet named at St. Peters on 5 February 1620.
- Isaac Allerton had a sister Sarah in Leiden, who married Mayflower passenger Degory Priest.
- Isaac Allerton was one of the more active and prominent members of early Plymouth. He was elected as Governor Bradford's assistant in 1621, and continued as an assistant into the 1630s.
- In the 1623 Division of Land, Isaac Allerton received 7 acres. In the 1627 Division of Cattle he is listed with wife Fear and children Bartholomew, Remember, Mary and Sarah.
- In 1627, he was sent to negotiate the Plymouth Colony's buyout of the Merchant Adventurers, the investors who had originally funded (and had hoped to profit from) the Colony. The Colony was about £2,500 in debt; a small group of Plymouth residents, including Bradford, Brewster, Standish, Fuller, and Allerton, sought to assume the debt themselves in return for the rights to profit from the company. Allerton was sent to England to negotiate further, and would return to England on several more occasions. Unfortunately for the others, Allerton began to use his "free" trips to England to engage in some private gains, purchasing goods and selling them in Massachusetts Bay and Plymouth. He also used his capacity as Plymouth's designated negotiator to engage the Colony in a number of unapproved money-making schemes; he went so far as to purchase ships (which he partially used for his own private trading), and to attempt to negotiate grants and patents for trade—all at great cost to the company and none of it approved by the others back in Plymouth. When his trading schemes failed, the Company found itself in far greater dept than when that ever started.
- When Allerton's wife, Fear died at Plymouth about 1634, and with the general ire of the Colony against him, he had little reason to stay. He moved to the New Haven Colony, and by 1644 had remarried to his third wife, Joanna Swinnerton.
- On 6 May 1635, it was recorded in the Massachusetts Bay Colony Records that Mr. "Ollerton" had given to Moses Maverick, his son-in-law, all his houses, buildings and stages at Marblehead.
- On 26 September 1639, Isaac Allerton deposed at Boston calling himself of New Plimmouth aged about 53 years.
- Under date of 17 Feb 1644/5 Governor Winthrop recorded "Mr. Allerton coming from New Haven in a ketch, with his wife and divers other persons, were taken in a great storm at northeast with much snow, and cast away at Scituate, but the persons all saved."
- Isaac Allerton was called "of Newhaven Merchant" in a 13 October 1646 letter of attorney.
- On 27 October 1646 Isacke Allerton of New Amsterdam in the province of New Netherlands, merchant, confirmed to son-in-law Thomas Cushman of New Plymouth a debt of one hundred pounds owed to Isaac by John Coombe.
- On 4 October 1660, Isaac Allerton (the son) granted to his mother-in-law Mrs. Johanna Allerton the house in New Haven where she now dwells during her life and then to his daughter Elizabeth Allerton and her heirs. The deed was not witnessed, so on 10 March 1682/3 Isaac Allerton confirmed the deed.
- On 19 May 1684 Elizabeth Eyre formerly Allerton, now wife of Simon Eyre deeded to her husband, her reversion in a house and lot her grandmother Joanna Allerton "lives in."
- Isaac Allerton remained an active trader, and did regular business with the Dutch in New Netherland in modern-day New York. Records of his trading can be found in numerous other colonies as well, including Virginia and Barbados.
