Suriyothai (สุริโยทัย, d. Seeing her husband about to be killed by the Burmese viceroy in an elephant duel, she drove her own elephant between them and was cut down in his place. The most revered queen in Thai history.
Suriyothai 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 Suriyothai reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
