I'm trying to find out the Civil War record of my great grandfather, Moses Adam Knowlton, of Essex NY (1828-1909). Family lore has him as part of the Union Naval blockade of the South, but I cannot find out if he was in the Navy, or a civilian skipper or crew member. He returned to Essex and later Vergennes VT where he was a steamboat pilot on Lake Champlain. One of his boats was the "Nymph." He is buried in Lakeview Cemetery, Essex. Bill Knowlton
