About the name
Afonso is the Portuguese Alphonse, from a Visigothic compound usually read as adal, noble, plus funs, ready or eager — though the first element may instead be hathu, battle, and the Germanic name stock is worn enough that both readings survive.
Afonso Henriques made himself the first King of Portugal in 1139 and the name has never been ordinary since. It is the closest thing Portuguese has to a founding name, which is why it reads as weighty there and merely unusual abroad.
