Here are my notes about this document:
Document received by mail from NYC Dept. of Records, March 2016.
The informant (i.e., the person who provided the non-medical information for the death certificate) is Regina's husband, Morris Holzman.
Their address is 793 Crotona Park North, Bronx. See this address today in Google Maps.
This document says Regina is 60 years old and has been in the U.S. (and living in New York City) for 58 years.
Her parents' names are as expected: David Weiss and Helen Greenbaum.
This shows that Regina died in a Bronx hospital, from lobar pneumonia, and that she had diabetes.
