Considering that (1) 'k' didn't exist in classical Latin and is usually rendered as 'c' in latinized words, and (2) the origin of Catherine is Greek καθαρός (katharos), pure, with an 'a' in the second syllable of the original stem, Catharina seems to be a quite reasonable latinized form, that could be used for any variant of the name.
I wouldn't regard the use of catharinae as being necessarily indicative of the actual spelling of the name of the dedicatee.
