I love
Catherine, and
Cate would be my favourite but it still does nothing for me. Thus, if I used
Catherine it would have to be in the mn spot. Catie's too cute, Cath's too informal,
Cate isn't as preferable to
Kate, and
Cathy's too dated.
I really like
Theodore, and though I'm iffy about
Edward, all of the
Edward nicknamed could apply to my prefered
Edgar.
