Help identifying a historical royal bride?
I apologize for being so vague with the details, but I was reading a Wikipedia article about a young, royal couple and didn't bookmark it correctly. Now I can't stop thinking about the story, and it's driving me crazy!
It pertained to a duke or king who fell in love with a young girl (aged 12-14). She was ill, and therefore her father (and the young man's retinue) encouraged him to look elsewhere, but he was in love with the girl and wed her anyway. She died shortly after their marriage (fever? pneumonia?) in his castle, and he was understandably heartbroken. I do not think he remarried.
I'm assuming it was around the medieval area, but could have been slightly later.
Does this ring a bell to anyone? I would love to identify the girl.
