I don't know why, but I love figuring out stuff like this. One of my classmates calls me a "church nerd."
Of all those I have baptized thus far as a cleric of the Roman rite:
Have a biblical or saint's first name: 43%*
Have a biblical or saint's name somewhere among their given names: 71%
Have no biblical or saint's name at all: 14%
Apart from surname,
have three given names: 12%
have two given names: 81%
have one given name: 7%
Most popular names:
For girls, Madison (15%)
For boys, Matthew (14%)
*I'm judging this in the most expansive sense, i.e. accepting as saint's or biblical names all versions, derivatives and cross-language drifters, like Jesús or Joshua for Jesus, Grace (a very New Testament word), Christine in it's various spellings, Sean for John, Marie, Mariah, etc.
