Hamutal (חֲמוּטַל) means "father-in-law is dew" in Hebrew. In 2 Kings 23:31, Hamutal was the daughter of Jeremiah of Libnah and the wife of King Josiah — mother of Kings Jehoahaz and Zedekiah of Judah.
Rare but iconic in biblical scholarship.
Hamutal 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 Hamutal reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
