There is an excellent website at www.dnaco.net/~csmartin/20th.html for the 80th NY Infantry 1st Brigade 3rd Div. 1st Corps, organized 1851 in Kingston and known as the Ulster Guard, 20th NY State Militia. They fought gallantly at Antietam, Gettysburg, Fredericksburg and 2nd Bull Run as well as many other battles. The website includes the Roster and I found many familiar surnames there. Well worth a look. Terri
