Bega is from the Old Irish bec (small, little). Saint Bega (7th c.) was the Irish princess who, fleeing an arranged marriage to a Viking, landed on the Cumbrian coast and founded a hermitage — the town of Saint Bees in Cumbria is named after her. Patron of the Lake District.
Featured in the medieval Life of Saint Bega.
Bega does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Bega reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
