Help a Reader with a Curious Problem

A reader writes:

I’m in my early 30s now but being a cradle Catholic I was confirmed at the usual time – 14 years old, when my faith was rather casual.

At that time, with my grandfather as my sponsor, I took my other, late grandfather’s first name, John, as my confirmation name.  Of course, the only attachment I had to John was via my grandfather — I didn’t pick a particular saint to associate with that name.

Now that I’m older and more serious, I was hoping to attach a particular Saint John to my name and incorporate him into my prayer life.  I know of many good Saints John but on the off chance that your readers might be able to point me to some of the other non-standard Saint Johns (or Blesseds, etc.) I figured a debate over (or at least stories about) various Johns might make interesting combox fodder for your blog.

I’m partial to St. John the Evangelist.
