The 1910 census shows Dora Jane as being a widow, as
does the 1920 census.  Ergo, Henry Nathan died on or
before 1903.

Henry E. and Catherine are shown on the 1920 census,
taking care of their mother; he is 27 and single, and
she is 20 and single.  Henry E. is shown as a steel
mill laborer.  The family is till in Ward 10 of
McKeesport.
