Is it possible that Henry Wendelken is buried with John Wendelken (1855-1932) in Flower Hill? You had a photo request for John posted on FindaGrave.com which I did the last time I was at Flower Hill and John did not have a marker. Perhaps check with the cemetery office to see what plot Henry was in. The one I photographed for John was Block O, Row 7, Grave 33.
