Alberich is a sorcerer dwarf who guards the treasure of the Nibelungen in the medieval German epic the Nibelungenlied. The dwarf also appears in Ortnit as a helper to the hero.
In England the name became rare after the Middle Ages, but it was revived in the 19th century, more commonly in the spelling Beatrice. Famous bearers include the British author and illustrator Beatrix Potter (1866-1943), the creator of Peter Rabbit, and Queen Beatrix of the Netherlands (1938-).
A known bearer of this given name was the Austrian-Hungarian (but of Polish descent) flying ace Godwin von Brumowski (1889-1936).
Roland was an 8th-century military commander, serving under Charlemagne, who was killed by the Basques at the Battle of Roncevaux. His name was recorded in Latin as Hruodlandus. His tale was greatly embellished in the 11th-century French epic La Chanson de Roland, in which he is a nephew of Charlemagne killed after being ambushed by the Saracens. The Normans introduced the name to England.
