On June 18, 1833, Lossing married his first wife, Alice Barrit, who died in 1855. On November 18, 1856, Lossing married his second wife, Helen Sweet. In 1868, the Lossings moved to a manor in
Dover, New York, that Helen had inherited from her family; they called this The Ridge, but by later custom it has come to be known as Lossing Manor. There Benson had built a fireproof library to house his collection of over five thousand books and documents associated with the American Revolution and the framing of the
Constitution. Lossing was actively involved in charitable, civic, literary, and historical societies, most notably serving as a charter trustee of Vassar College in Poughkeepsie. He died at home in
Dover Plains, New York, on June 3, 1891. A written reminiscence of the Lossing family and life in 19th century New York was assembled by his son, Thomas Sweet Lossing; edited by his great-nephew, Peter Hannaford, it was published as
My Heart Goes Home in 1997 (Purple Mountain Press, Fleischmanns, New York). == Works ==
