Catherine is my favorite as I've got a reletive named
Catherine. So if I met somebody named
Catherine,
Katherine,
Kathryn,
Catharine ..., I would assume it would be spelled
Catherine.
I don't really like names starting with 'K' in general, and
Kathryn looks horribly misspelled so I don't like
Kathryn,
Katherine, or
Katharine.
I do like the name
Catharine, however.
My relative,
Catherine, went by
Cathy in her youth. I know a
Kathryn who simply goes by
Kathryn. I know a Swedish girl named
Catharina who goes by
Cajsa.
