There’s an interesting item in the 1964 blog (from the Center for Applied Research in the Apostolate).
They looked at the US Social Security Administration statistics on popular baby names.
Where is Mary? Not in the top ten. From 1910 to 1965 Mary was either the #1 or #2 name for girls in the U.S. In 2009, this name dropped out of the top 100 for the first time (currently #102). By comparison, Joseph has remained consistently popular. Although at #16 in 2009 this is the lowest rank for Joseph since 1910.
They also considered the names of the evangelists and provide a chart showing how the names have trended.
Finally they add:
…"worship attendance does increase Catholics’ likelihood of choosing specific names that are disproportionately common within their tradition… They estimate that 50% of females named Mary (or Marie, Marion, Maria, Maryann, etc.) in the United States were raised Catholic (p.221). Females with the following names were least likely to have been raised Catholic: Tamara or Tammy (14%), Shirley or Shirlene (15%), Bonnie (16%), Brenda (16%), and Joyce (18%) (p.222).
How are things in your family? Are you named for a saint? Have you named your children after saints?
