Sogol is from the Persian سوگل (Sōgol — little flower, dear flower, beloved one) — from Persian gol (flower/rose). Sogol is one of the Persian feminine names — central to traditional Persian heritage. Persian feminine name reflecting Persian floral-aesthetic heritage.
Sogol 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 Sogol reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
