A variant is Averell. A famous bearer of the name is W. Averell Harriman, Governor of New York (1955-59) and Ambassador to the USSR (1943-46) and the United Kingdom (1946).
People often regard the meaning of this name ('Boar warrior') as vulgar, but they fail to consider what the boar meant and symbolised for the Anglo-Saxons.
The boar was one of their most sacred animals; it was held in reverence as a creature of great strength/power and a talisman of divine protection in battle. It has been linked to the god Ingui-Frea.
