Notes http://www.townofmonroeme.net/id34.htmlhttp://www.townofmonroeme.net/id34.html John Couillard was a native of France and born in the year 1655. Early in life he entered into the Marine Service and subsequently enlisted on board a French frigate which, in one of the wars of the 17th century between France and England, had an engagement with an English frigate along the coast of Massachusetts during which the two ships were brought into immediate contact by grapplings for the purpose of boarding. The station of young Couillard was that of Captain of the Main Top, and while the two frigates were thus boarded together, he passed from the French ship to the English vessel. The frigates soon separated without capture on either side leaving Couillard prisoner on board the English frigate, which soon put into Boston Harbor, where Couillard was discharged. After the peace was declared and the prisoners freed, Couillard proceeded to Cape Ann where he met a young woman, married, had a family of children, and resided for a number of years. From Cape Ann he emigrated with his family to the Kennebec region of Maine and purchased a farm, built a house, and settled upon Arrowsic Island, then part of Georgetown. He continued to reside on his farm, employing himself in husbandry and fishing until a disease took him in the year 1770, at the age of 115 years. It is interesting to note that John's second wife, Sarah Rankin, was the mother of his son's wife, Mary Mock.
