I know a person named Casia (with a C) because her twin's name is Isaac and it's an anagram.

Well my name is also spelled Kasia and I'm not Polish nor have knowledge of the Slavic language but I pronounce my name as Asia with a "K"... sorry if that's strange or rains on anyone's parade.
My name is Kasia. I'm Polish but grew up in the States. I have always LOVED my name. Yes, people butcher it ALL the time, but it never was enough to make me dislike it. If it was socially acceptable, I'd even consider naming my daughter it.

One of the most beautiful, good-natured girls I know is called Kasia. We are very close and I love her, so I love this name. Very often, teachers at school mispronounce it as 'KA-SEE-AH', which is also quite pretty in my opinion. :)

I love this name and Katerina. If I had a daughter I would name her Katerina and have her go by Kasia. Such pretty names!
I'm Polish and everyone in my family calls me Kasia. I love the name, I think it's very feminine and simple but not dull. The pronunciation is: Kah-shya, not Kah-shah. I think it's something only people with some knowledge of Slavic languages can pick up, though.
My Polish great-grandmother is named Catherine, but called Kasia within the family. She pronounces the name KAH-sha, but the "sh" sounds different than the typical English "sh". Its pronunciation falls somewhere between "sh" and "j", similar to the "j" in Jacques.
Kasia is pronounced KAH-sha. [noted -ed] As a child all my dolls were named Kasia. Oddly it was the name that most children in Poland chose for their dolls. I suspect because the sound of 'Kasia' has an incredibly sweet and snuggly feel to it.
