Olufunmilayo is from the Yoruba Olúfúnmiláyọ̀ — Olú God/Lord + fún gave + mi me + láyọ̀ joy — God has given me joy. Olufunmilayo is one of the Yoruba feminine names — central to traditional Nigerian + West African heritage.
Olufunmilayo 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 Olufunmilayo reduce to 2, The Peacemaker. This is a traditional interpretive system, not a factual claim about the name.
