The National Cyclopaedia of American Biography, Volume 6 (Google eBook), J.T. White, 1896, from the biography of descendant Henry Clinton Backus:
Elisha, the great-grandfather of Henry Clinton Backus, took part in the battle of Bunker Hill, held the rank of major in the Revolutionary army and, in time of peace, emulated his forefathers by founding another town, that of Manlius in Onondaga county, NY. His son Elisha was a colonel in the American forces during the war of 1812.
Note: I am a Backus descendant, too. Elisha Backus and I share the first three ancestors, William Backus 1, Stephen 2, and Timothy 3. My lineage starting with Laura (Backus) Richmond.
