Even though I'm not Estonian at all, I have to say Kadri might be the prettiest form of Catherine/Katherine I've come across. I especially like the hyphenated name Kadri-Leena, which I added to this site.

Kadri is widely used in Estonia and many girls born in the beginning of the 1990's were named Kadri. I myself know at least six or seven Kadri's.
