Ninhursag (𒀭𒊩𒌆𒉺𒂅) was the Sumerian mother goddess and "Lady of the Mountains" — among the seven greatest deities of Sumer. Considered the mother of all living beings; her temple in Eridu was one of the oldest in Mesopotamia.
Rare but iconic in Sumerian studies.
Ninhursag 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 Ninhursag reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
