Mount Judah Cemetery is in Ridgewood, which is in Queens (though the closest subway stop is in Brooklyn). The website includes a burial search, which provides the location of the burial of the person you're looking for. The About Us page includes information that helps a searcher locate where in the cemetery the loved one is buried.
Because of the wealth of resources available to FindAGrave volunteers, I'm a bit surprised that there are currently over 800 photo requests for this cemetery. I encourage FindAGrave volunteers local to this area to help fulfill these requests.
My husband's maternal grandfather has a sister and brother buried at Mount Judah in the Dr. Igel Lodge Society, one of the dozens of societies in this large cemetery.
Good thing I did.
