Ariel, the son of James Ballou, inherited the northern part of James’s land, a large farm lying on both sides of the Massachusetts and Rhode Island border where Wrentham and Cumberland adjoin, and his farm and homestead were eventually inherited by Alfred. Alfred was an officer in the local militia and he was also the elder half-brother of Adin Ballou, the author and compiler of “An Elaborate History and Genealogy of the Ballous in America” 
Adin Ballou (1803-1890) was a Universalist, later Unitarian minister and a prominent proponent of pacificism, socialism and abolitionism. He was the founder of the Hopedale Community near Worcester, a short-lived utopian community which incorporated some of the concepts of a mill village with “practical Christianity.” Leo Tolstoy admired some of his writings, and sponsored their translation into Russian.
