Catalina

In Castillian, her name is Catalina. She is better known, however, as Catherine of Aragon.

An interesting post on Henry VIII's Queen Consort from The Mad Monarchist begins this way:

"One of the greatest English queen-consorts and a longtime favorite of mine Queen Catherine of Aragon was a 'woman among women' and it would be hard to imagine how she could be capable of such inner strength, such devotion, tenacity and even forgiveness and even fighting spirit without keeping in mind that she was very much her mother's daughter and that mother happened to be the formidable Queen Isabella of Castile. She was born in 1485 even as her parents Ferdinand of Aragon and Isabella of Castile were fighting the last battles of la Reconquista; the longest war in history, to liberate Spain from the Moors. From an early age her character was shaped by two guiding forces; her fervent Catholicism and her betrothal to HRH Arthur, Prince of Wales, son and heir of King Henry VII of England. She thus saw it as her lifelong destiny to be Queen of England."
