Sumaya is from the Arabic Sumayya (سمية — elevated, exalted, proud). Sumayyah bint Khabbat (d. Sumaya Genç — Turkish handball player. Sumaya Mukhtar — Sudanese-American figure. Princess Sumaya — Arab-Muslim royal heritage naming.
Sumaya 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 Sumaya reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
