This name is different than the usual popular selections, and that's what makes it great. I always wonder why people tend to use the same names over and over again -- why not go for something unique? ("Unique" as a name just does not cut it. It is no longer unique. There are dozens of little Uniques out there.) Use something like "Afonso" instead!
Afonso was the second son of King Afonso II of Portugal and his wife Urraca of Castile. After his brother died without issue, he became King Afonso III of Portugal.
Afonso (1475-1491) was the oldest son of King Joao II of Portugal and his wife Leonor. He was supposed to become King, but died age 16 in a horse accident.
This name makes me picture an adorable little boy named Alphonso or Alphonsus who can't quite pronounce it yet. I hate those names, but this one is heart-meltingly cute. I hope I never meet a man with big brown eyes and this name. I'd be in trouble ;)
