In reply to Sherri Bobish's 1940 census:
The Evening Star  11 Dec. 1940 lists Max Greenspun age 65 in the listing of deaths on p. 8.  source:  newspapers.com
Therefore, this Ida Greenspun would have likely been a widow in 1942.

The 1940 address is 2700 N nw, Washington,  DC.  I found this Max and Ida Greenspon at this address in DC city directories as early as 1932.
