Christopher Hatch (ca. 1751-1819), wife Elizabeth, was a Boston merchant and Loyalist who was banished from his home in 1778. He served in the Loyal American Regiment and settled at St. Andrews, New Brunswick in 1783. He established shops at St. Andrews, St. George and Campobello Island. He was a close associate of Edward Winslow who described him as one of the "principal dealers" in plaster on Campobello. As such he may have been associated with David Owen. He was also a magistrate, colonel of militia and Assistant Deputy Surveyor-General of the Kings Woods.
Harris Hatch (1780-1856), Christopher's son, married Ann Whitlock, daughter of William Whitlock of Saint John, July 1803. They had at least nine children - Josephine (Capt. Henry Bernard), Isabella (David Green), Augusta Jane (Peter Marter), Emily (Charles Powers), Harris, Wellington (Susan Jones, daughter of Thomas Jones, High Sheriff), Christopher (Susan McGrath), Charles, and Edwin F. (Ann ----). He was a justice of the Inferior Court of Common Pleas, Surrogate and Registrar of Deeds and Wills for Charlotte County. In 1839 he was appointed to the Legislative Council of New Brunswick and sat as a member of that body until his death. He was an officer in the militia and a director of the Charlotte County Bank. He invested in the St. Andrews Steam Mills and Manufacturing Company and was a founder of the St. Andrews Whale Fishery Company. He was a leading promoter of the rail link between St. Andrews and Québec.
His son, Harris Henderson Hatch (1811-1894), the eldest of the family, succeeded his father as Registrar of Deeds and Wills for Charlotte County in 1856, and was concerned with legal matters until his father's death when he took over the family's business affairs. He expanded the family interest in the railway by acting as a shipping agent and later dealer in forest and agricultural products. He owned at least one sailing ship and invested in gold mines in Nova Scotia. He was twice married, first to Mary Campbell and secondly to Mrs. Cordelia Fowler, sister of Admiral Shortland of the British navy. He died with no extant offspring and was survived by his second wife and two sisters.
