I like
Catherine, but I think I'm more attracted to its variants (e.g.
Kathleen,
Karina, and Cateau). I loved it since I was little, because it is one of the first Western names that I've ever heard, I guess lol.
From the Katherine/Katharine/Kathryn, I like
Katharine the most. I think it sounds very authentic and looks really nice with the K at the beginning.
I might pair
Catherine as
Catherine Belle,
Catherine Marie,
Catherine Diana,
Catherine Zenobia,
Catherine Wanda,
Catherine Ophelia, or
Catherine Shania.
