Ahab

Means “uncle”, from Hebrew אָח (‘ach) meaning “brother” and אָב (‘av) meaning “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. Herman Melville later used this name in his novel Moby-Dick (1851), where it belongs to a sea captain obsessively hunting for a white whale.
