Elias Nason, The Life and Times of Charles Sumner: His Boyhood, Education and Public Career.

[14] William and Mary Sumner, early removed to Lancaster with other Christians for “the gathering of a church.” Remaining there until the town was destroyed by the Indians, he returned to Milton, where he died May 26, 1698. His son William, it is supposed, married Esther Puffer of Dorchester, Jan. 2, 1697, and had, inter alios, Seth, born Dec. 15, 1710; and married for his second wife Lydia Badcock in 1742. He was the father of thirteen children; among whom Job, the fifth son, born April 23, 1754, graduated at Harvard College in 1778, and became a major in the Massachusetts line of the army of the Revolution. He was a man of ability, “sustained the reputation of an attentive and intelligent officer,” and died from being poisoned “by eating of a dolphin,” Sept. 16, 1789; leaving a son Job, who was born at Milton Jan. 20, and baptized March 17, 1776. His name was subsequently changed to Charles Pinckney. He was educated at Harvard, and possessed considerable poetic ability. At his graduation he delivered a commencement-poem on “Time,” together with a valedictory class-poem, both of which possess some degree of merit, and are still preserved. In the last year of his collegiate course he published a poem entitled “The Compass,” in which occurs a quatrain that seems to indicate, to some extent, the leading idea, the aspiration, and the effective lifework, of his illustrious son.
