Henry Alexander Scammell Dearborn (1783-1851) was born to Dorcas Osgood and Henry Dearborn, the famous Revolutionary War figure and Secretary of War under Jefferson. He graduated from William & Mary in 1803 and practiced law in Salem, Massachusetts. In 1806, he was appointed superintendant of new fort construction in Portland, Maine. During the War of 1812, Dearborn served as brigadier general of the local militia, and served as collector of customs in Boston until his removal in 1829, during the Jackson administration. He held several offices in local government, such as state representative from Roxbury, member of the Governor's Council, and delegate to the state constitutional convention, and served one term in the U. S. House of Representatives (1831-1832). Dearborn was appointed adjutant general of Massachusetts from 1834 to 1843, and was elected mayor of Roxbury, Massachusetts, in 1847, a position he held until his death in 1851. In addition to his political pursuits, Dearborn was president of the Massachusetts Horticultural Society, and was the author of several books. He died in Portland, Maine, in 1851.
