I like
Christina and
Kristina both quite a lot but I thend to lean towards
Christina, because I would want to use the nn
Christie spelt that way. It's definitely ready for a comeback and while it may have ben more popular in the eighties this name is definitely a classic, it has never been below the top 500 in the US. It's not my favorite name, but I might use it as a mn in honor of my Aunt
Christine.
I know 3 Christinas and 1
Kristina all of them go by their full names. Two of them are named
Christina Michelle.
I think
Christie a lot, but not really any of the other nns.
I can't even guess at the swings in popularity.
