Philip Wohlgemuth b 1908 L.I., NY m-Gertrude Ruff

Looking for information on this couple. They would have been Gt Aunt & Uncle to my husband. I know Gertrude died 1990 in Maspeth, Flushing, NY. I don't know where she is buried. I'm assuming Philip has passed by now and know nothing on him for dates, his parent's, siblings, etc. Any help would be appreciate.
