Okay. It's really hard to describe the vowel sound considering I don't know what kind of accent you might have but it's somewhere between the a in
Kate and the e in pet. I *believe* the final e would be pronounced also (it is in
German words but names can be a little different) so it would be like kayteh or kehteh (second e like in egg). Anyways, how did your mother pronounce it? That's the pronunciation I'd use.
