Delaware County, NY Genealogy and History Site

I only know the names of two. They are John Howard Whitney (b. 12 Feb 1873) in the back row far left, and also in the back row sitting next to him is his brother Homer Freeman Whitney (b. 20 Mar 1874.) They were both born in Union Grove, Delaware County, New York which is now under the Pepacton Reservoir. --Regards, John Whitney, June 1, 2001
