Fridbjorg is a name of Icelandic origin, meaning a guardian of peace.
Fridbjorg is a compound name. Its parts are friþu + bjǫrg — each an attested element with a recorded meaning of its own.
Fridbjorg 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 Fridbjorg reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
