Ahalya (अहल्या) means "unploughed, beyond reproach" in Sanskrit. The wife of the sage Gautama in the Ramayana — tricked by Indra into adultery, she was cursed by Gautama to become stone.
Featured in the Ramayana and many later texts.
Ahalya 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 Ahalya reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
