Jedidah (יְדִידָה) is the Hebrew word for "beloved." In 2 Kings 22:1, Jedidah was the daughter of Adaiah and mother of King Josiah — the reformer-king who restored worship of YHWH.
Used widely in modern Israel.
Jedidah 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 Jedidah reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
