Nothing definite, but would there be a connection to AL DUBIN, born 1891 in Switzerland, died 2-11-45, in NYC, then apparantly buried in Philadelphia? (I checked PHILADELPHIA OBITS, 1940/50s for this lead).
If there is a connection, perhaps they share a family plot.
AL DUBIN was a man of renown, having co-composed at least two classic songs, TIP TIP TOE THRU THE TULIPS and WE'RE IN THE MONEY... ...
His burial site should be fairly simple to locate.
