Morton Simon refered to his aunt, Jeanne Simon, daughter of William and Bessie. I presume that this is the same as Jenette Simon referred to in both the 1910 and 1920 U.S. Census as daughter of William and Bessie.

Also, Mort wrote a letter to her after Eva Simon died in November, 1980. At that time, Jeanne was living in Atlantic City, NJ according to Wilma Drob Clauson. [676]

1920, 1930 and 1940 Census list Jeanne Simon, daughter, living with Betsy Simon at 1800 Locust St., Pittsburgh, Allegheny, Pennsylvania, USA. [1561]
