I love
Kirsten. It sounds warm and Christmas-y. I'm neutral on
Kristen but it just not my taste,
Kristen is also an Indonesian word for
Christian.
Kjerstin looks interesting but I'm not into it. For me
Tineke sounds like an old/middle-aged women's name as our country (Indonesia) were colonized by Netherlands until 1942. Same goes with
Anneke, Mareyke, Linneke, Jultje, Zusje, Dintje, and Vonneke.
