Phooey! The death certificate that I ordered for the Joseph Rabinowitz buried Sept. 2, 1920 at Mount Hebron arrived yesterday. He was age 46 and had been in the U.S. for 14 years—originally from Russia. Son of Elias Rabinowitz and Ella Tarman (?). Resided at 587 Beck Street in the Bronx before his 10-month convalescent stay at Montefiore Home & Hospital. Diagnosis of his last illness was chronic endocarditis.
So that's not our guy. Beautiful embossed-seal reproduction of the original, though. The search goes on.
