Ahinoam (אֲחִינֹעַם) means "my brother is pleasant" in Hebrew. Two biblical women bore the name — King Saul's wife (1 Samuel 14:50) and David's wife from Jezreel (1 Samuel 25:43), mother of Amnon, his firstborn.
Rare but iconic in biblical scholarship.
Ahinoam 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 Ahinoam reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
