Angharad is from the Welsh an- (much) + câr (love) — "much loved." Angharad ferch Owain — Welsh medieval princess (12th century); wife of Rhys ap Tewdwr, King of Deheubarth (south Wales). Angharad Mair — Welsh broadcaster. Angharad Tomos — Welsh-language novelist. Angharad Wood — modern Welsh figure.
Angharad is a compound name. Its parts are radŭ — each an attested element with a recorded meaning of its own.
Angharad 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 Angharad reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
