Aslaug combines the Old Norse áss (god) and laug (consecrated, betrothed) — meaning "god-betrothed." In Norse legend, Aslaug was the daughter of Sigurd and Brynhild, and the second wife of Ragnar Lothbrok.
Aslaug is widely used in modern Scandinavia.
Aslaug 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 Aslaug reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
