The name is Finnish and can either be considered a contracted form of Kirsten, a diminutive form of Kirsikka (which is Finnish and means “cherry,” or from a Finnish word for frost. It is sometimes used in conjuction with Marja, Kirsi-Marja/Kirsimarja, which also happens to be a Finnish synonym for cherry. Its designated name-day is July 24.
As summer comes to a close, I almost forgot to post about this lovely gem. Find Cherry too tacky as a given name? Then why not this Balkan beauty. The name comes directly from the South Slavic word for the cherry, and it a fairly common name in the former Yugoslav Republic. In Slovenia, its the name of a mountain Gora Visnja, known as Weichselburg in German.
