About Thomas Dimon

THOMAS DIMON is the first provable ancestor of the Dimon family of Fairfield, Fairfield, CT. He settled in Fairfield prior to 1650, but little is his history and his ancestry is a matter of conjecture. The name Dimon, also spelled "Dimond" and "Dymond" in early Connecticut records, suggests British origins. We might therefore speculate that THOMAS was born in England shortly after 1600 and immigrated to New England as an adult. When THOMAS DIMON settled in Fairfield, the town founded in 1639 on Long Island Sound was growing steadily. Grain and timber were Fairfield's agricultural staples and the basis of an early export business. Excellent harbors in the town's immediate vicinity encouraged commerce and gave Fairfield the resource it needed to become a navigational center for all of the western Connecticut colony. THOMAS profited from Fairfield's costal trade both as a mariner and a ship owner. In the early 1650's he owned and operated a vessel valued at about £200. When the boat "suffered a great loss by fire", in 1655/56, one of his friends in Fairfield wrote the Governor at New Haven to ask for help in raising money for THOMAS' relief. It is not known if any relief was actually received by THOMAS. He died in the fall of 1658. His property was inventoried on Oct. 19, 1658. Since no mention is made of his wife in his will it is assumed she predeceased him. (2)
