No.  His father's name was Otto

Hi      I don't know the age but there was an OTTO GRUBER (6-5-1908-9-1978) who died in Patchogue, LI, 11772. You might check Suffolk County obituaries or funeral parlors in that area for the obituary that should list surviving relatives and city locations.  Warren Kessler PI of S. Lake Tahoe, CA who was born in the Bronx 1931 and lived there until 1955. DeWitt Clinton / PS86. [email protected]
