Mellenville Union Cemetery is located on
Route 217 east of
Hudson, NY. It currently is being used and an association takes care of it. The Town of Claverack would have more information. I've forgotten if Mellenville was incorporated as a village. If you're traveling east from
Hudson, the entrance is just past Speed's Garage on the left. There is a creek on the right-hand side. If you go to far, you come to a Y in the road and the road starts to go uphill.
I grew uphill from Mellenville in Philmont.
