I love
Katya,
Ekaterina,
Catriona and
Karen.
I think I would like
Cathy more if I didn't have massively bad family associations with that name.
I only like
Cathy and
Catherine with a C, for some reason.
I also know Catherines that go by things such as
Terry,
Trina,
Tina,
Thea,
Kitty,
Erin, and Cat.
I like
Tina,
Thea,
Kitty and Cat.
