Means "uncle", from Hebrew אָח ('ach)
"brother" and אֲב ('av)
"father". This was the name of a king of Israel, the husband of Jezebel
, as told in the Old Testament
. He was admonished by Elijah
for his sinful behaviour. This name was later used by Herman Melville in his novel 'Moby-Dick' (1851), where it belongs to a sea captain obsessively hunting for a white whale.
