An interesting biography. Mary's niece Mindy was a year behind me in high school, i.e., WAHS class of 1969.
As for her name, see "There Really Was Something About Mary"
I don't know how common it is anymore, but when I was a kid, it wasn't unusual for a girl to have a "double" first name, e.g., Mary Sue, Betty Jean, Mary Ann(e), Ann Marie. Mary Jane was the most common one that I encountered in grade school.
Mary Jane first makes its first appearance on the Social Security Administration's list of 1000 most popular baby names for girls in 1914, at #949. It reached as high as #463 in 1923 before dropping to #812 by 1932. Its best year was 1944, when it reached #501. It didn't make the last from 1956 to 1958 and then again for a much longer stretch, from 1966 to 2004. It currently ranks #888, so I guess we can say Mary Jane is making a modest comeback.
A big hit when the class of '42 graduated.
