The following biography of my grandfather, Lieutenant Governor John Latta, Branch 3, was originally published in 1918 in Old and New Westmoreland, Capt. Fenwick Y. Hedley, editor, by the American Historical Society, New York, Volume III, pages 4-5. It is interesting to note that Robert H. Latta corresponded extensively with my grandfather in his effort to establish branch assignments and possible linkages. Corrections are noted in [ ].
