Nehushta (נְחֻשְׁתָּא) is from the Hebrew nechosheth (bronze, brass). In 2 Kings 24:8, Nehushta was the daughter of Elnathan and the mother of King Jehoiachin of Judah — taken into Babylonian exile with her son in 597 BCE.
Rare but iconic in biblical scholarship.
Nehushta 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 Nehushta reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
