Omowunmi is from the Yoruba Ọmọwùnmi — ọmọ child + wù mi desired by me — the child I desired. Omowunmi is one of the Yoruba feminine names — central to traditional Nigerian + West African heritage. Yoruba feminine name reflecting Nigerian child-naming heritage.
Omowunmi 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 Omowunmi reduce to 6, The Nurturer. This is a traditional interpretive system, not a factual claim about the name.
