Aedon (Ἀηδών) is the Greek word for "nightingale." Daughter of Pandareus, who accidentally killed her own son Itylus and was transformed by Zeus into a nightingale — mourning him eternally with her song.
Aedon 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 Aedon reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
