Yes MMario, but are they a double-name Mary (Mary Beth, Mary Jane, Mary Lou, Mary Warren, Mary Margaret (me)) or just Mary? I haven't met a little girl named just Mary in many, many years. If you know one, tell her how special she is, and hello from me.
I now live in a heavily Catholic town. One of my friends, Mary Annette, tells the story of the old priest here who used to baptize all, and I mean all, little girls with the first name of Mary. He had to slip it in under his breath. Many families had little girls with four names, all with the first name of Mary!
