1 James 843,189 Mary 625,464
9 Mark 382,369 Nancy 286,725
I am among the #1, but I got it honestly, with both grandfathers having that name, and one gr-gr-grandfather. My sister was named after the song Sinatra sung for his daughter, "Nancy With the Laughing Face." To what extent that was the reason for Nancy being #9, I don't know.
Wife and I are Mary - James
Hence the most common names of our decade
