David L Duff (1821-1876)

David L Duff was born December 19, 1821 in Huntingdon, Pennsylvania the son of John Duff and Winifred Couch. (This is concluded because it is stated that their son David served in the Mexican war and our David Duff is the one from Pennsylvania in that war, proved by the widow pension application.)
David served in the Mexican War with Co. B, Reg 2, Pennsylvania Volunteers from Dec 26 1846 to Jul 21 1848. He entered as a private and was promoted to Sargeant Major before release.
