Katyusha

All I see is the word "tush"...

I love this name! Reminds me of the Russian folk song 'Katyusha', it's about a girl called Katyusha longing for her lover who was at war, very lovely song. I think Katyusha suits a female of any age, from a young girl to a mature woman. This is of course, quite a unique name, but not too obscure or weird-sounding. It is quite easy to pronounce, and nicknames could be 'Katy' or 'Yusha'. I also love its association with Russian culture.
