Fresh Prince of Bel-Air alum Alfonso Ribeiro (a.k.a Carlton) and his wife Angela welcomed a baby boy on October 27th: Alfonso Lincoln Ribeiro, Jr. Alfonso joins big sis Sienna, 11, Ribeiro’s child from his previous marriage.

WHAT IT MEANS:  Nobel and ready

WHERE IT ORIGINATED: Alfonso is a Spanish and Italian form of the Germanic Alphonse, which was used during the time of the ancient Visigoths.

POTENTIAL NICKNAMES: “It’s not unusual” to choose rough and tumble Al, but Alfie is also totally fresh.

KNOW THIS: Eleven kings of Spain, six kings of Portugal and three kings of the Congo have been named Alfonso. It is currently the 793rd most popular name for boys in the U.S.

POP CULTURE CONNECTION: Along with his dad, baby Ribeiro shares his name with Alfonso Cuarón, director of Oscar-nominated film Children of Men and Harry Potter and the Prisoner of Azkaban.
