Task: Question Answering
Input (English): Passage: The film tells a fictionalized version of the Pilgrims' voyage across the Atlantic Ocean to North America aboard the Mayflower. During the long sea voyage, Capt. Christopher Jones falls in love with Dorothy Bradford, the wife of William Bradford. The love triangle is resolved in a tragic way at the film's conclusion.  Ship's carpenter John Alden -- said to be the first person to set foot on Plymouth Rock in 1620—catches the eye of Priscilla Mullins, one of the young Pilgrims following William Bradford.  Alden ultimately wins Priscilla in another, if subtler, triangle with Miles Standish.   Lloyd Bridges provides comic relief as the first-mate Coppin, and child star Tommy Ivo gives a touching performance as young William Button, the only passenger to die on the actual voyage across the storm-swept Atlantic, who, according to this film, wanted to be the first to sight land and to become a king in the New World. "I'm going to be the first to see land. Keep me eye peeled, I will. Then I'll be the first. It'll be like the Garden of Eden and I'm going to be the first to see it". 
Question: What is the last name of the person Miles lost Priscilla to?
Output (English): Alden.
