Kája

Kaja is also a pet name of Kajetana. My Czech mother is called Kajetana and she passed her name onto myself, I am Slovakian. It is a very uncommon name and I believe it is derived from the Italian name Gaetano. He was made a saint and our name day is therefore celebrated on 10th August according to the Catholic Calendar. It is pronounced to rhyme with "Hiya".
