- He married his cousin Mary; Bryce and Hugh were cousins, and Joseph and Mary were their children.
He participated in the French and Indian Wars and the Revolutionary War. He was a member of Col. Jonathan Mitchell's regiment during the Bagaduce Expedition. For a narrative of this battle (in two articles by Nathan Goold) which describes the participation of McLellans in it, see the New England Histories page. Here is Goold's description of him:
"Joseph McLellan, the commissary, was a Falmouth Neck man. He was the son of Brice and Jane McLellan and was born in Falmouth, in 1732. He married in September, 1756, Mary McLellan a daughter of Hugh McLellan of Gorham, Maine, and died July 5, 1820, aged eighty-eight years. He was one of the committee to prevent the landing of the rigging for Coulson's ship, at Falmouth March 2, 1775, committee of inspection, commissary of the Bagaduce Expedition, when he was appointed a captain of a company of carpenters. He was a lieutenant in Capt. Joseph Pride's company in Colonel Joseph Prime's regiment at Falmouth, in 1780, and commanded a company from December 6, 1780, until May 1, 1781.
"Capt. McLellan was first a mariner then a merchant. He was a selectman; county treasurer twenty-seven years, 1777-1803, and was a committee to build the courthouse in 1787. He was a prominent and respected citizen of Portland. His two sons, Hugh and Stephen McLellan were Revolutionary soldiers and became prominent merchants of Portland.
"His brother-in-law, Alexander McLellan, was a captain in charge of a company on the Expedition, and his brother William was master of the Centurion, which provided support on the expedition."
He was a prominent businessman in Portland after the war as a ship-owner, merchant, banker, and land speculator. He lost most of his wealth in the War of 1812.
