Amunet (Egyptian Imnt, "The Hidden One") was the Egyptian primordial goddess — feminine counterpart of Amun in the Hermopolitan Ogdoad of the eight gods of creation.
Amunet 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 Amunet reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
