Ada has two origins. In Old Germanic, it is a short form of names beginning with adel, meaning "noble" — like Adelaide, Adeline, or Adela. In Hebrew, Adah (עָדָה) appears in the Book of Genesis as one of the wives of Lamech and means "adornment" or "ornament."
Ada has been borne by some of the most consequential figures in the history of computing: Augusta Ada King, Countess of Lovelace — daughter of Lord Byron — is recognised as the first computer programmer for her notes on Charles Babbage's Analytical Engine in the 1840s. The Ada programming language, used in aerospace and defence systems, is named after her.
Ada 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 Ada reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
