Devakimayi is from the Sanskrit Devakīmayī.
Devakimayi 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 Devakimayi reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
