There's a comedy skit I remember seeing on TV, the comedian pretty much picked on variations of John that sound absolutely nothing like it - Esecially picked on Giovanni (something along the lines of "John has one syllable, and Giovanni has four!") and Jan ("The J is prononced as a Y and spelt out it looks like a girls' name")... I'll have to try to find it on YouTube

I didn't even think of the John-John thing, I always forget that Jack was originally a nickname

I told DH about Ianto being a dirivitive of Ifan, but he said he likes Ianto better and it flows with our surname a little nicer, so we're sticking with it. Here I was thinking it was just on our list, but no, apparently it's been decided - if we're having a boy it's Ianto Jack [surname]. Now to choose a girl's name What other TV shows do I like? Hmmmm....
