James is from the Hebrew Ya'aqov (Jacob — supplanter, one who follows) — traditionally male; entered top-1000 US girls' names in 2017. A modern American unisex baby name. King James Version Bible has been the English-language religious text for 400+ years.
James 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 James reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
