Shaurya is from the Sanskrit शौर्य (Śaurya — valor, bravery, heroism) — from Sanskrit śūra (hero/warrior). Shaurya is one of the Sanskrit feminine + unisex names — central to traditional Hindu warrior heritage. Sanskrit feminine name reflecting Hindu valor heritage.
Shaurya 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 Shaurya reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
