Very interesting. I like Waugh's "Campion" better than "Helena," though.
St. Helena is my Confirmation patron; I admire her for having produced a successful son :-).
Excellent choice! I went with Magdalene, as a reminder that one can overcome a sinful life.
Sorry to see that toay, the confirmandi are allowed to pick any name they wish, even if it is not that of a saint. With my students, anticipating that they wanted to pick unique names, I referred them to a complete list of saints dating back to the 1st century. That worked :-)
