BANKS, AARON.
The subject of this sketch was born in York, Maine, June 1, 1738. He married Mary Perkins, of York, who was a sister of John and Daniel Perkins, of Bagaduce. His death occurred on the ninth of August, 1823, at Penobscot. At the age of twenty-one years, Mr. Banks enlisted in the provincial army, for the defense of the colonies against the French and Indians. He was first stationed at Fort Pownal, and assisted in building that fort, early in the summer of 1759. In July of that year, he was transferred to General Amherst's command, and was with that command at the capture of Ticonderoga. He was also with General Amherst, at the capture of Montreal, September 7, 1760. A treaty of peace was made at Paris, between England and France, February 10, 1763. In consequence of this, Mr. Banks was honorably discharged, early in the winter of 1764. He and twelve others, were obliged to walk through the wilderness from Montreal to York, in the depth of winter, with no covering for their couch at night but the "starry decked heavens," and depending for their food upon the game shot upon the way. In the spring of 1765, Mr. Banks brought his wife and infant daughter to Bagaduce. He is said to have bought the farm first settled by Reuben Gray, on the Neck - being that now principally owned by Charles J. Abbott, Esq. - and to have built his house near the deep gully, not far from Mr. Webb's house. At the time of the skirmish at the half-moon battery, during the siege of 1779, Mr. Bank's house was burned by the Americans. He and his family were detained, for upwards of three weeks, as prisoners on board the British sloop North. After peace was declared, he moved to that part of Bagaduce which is now Penobscot, where he remained until his death. No descendants bearing his name exist at this day. His daughter Elizabeth, however, who was married to Colonel Jeremiah Wardwell, became the mother of a family of seven sons and four daughters. She died in Penobscot, November 26, 1853, aged 89 years, 5 months, and 21 days. 

He was married to Mary Perkins on 6 Jul 1764 in York, York Co., Province of Maine, Massachusetts.
