Yetunde is a Yoruba (Nigerian) name meaning "mother has returned" — traditionally given to a daughter born after the death of her mother or grandmother, expressing the belief that the soul has returned through the new child.
Yetunde 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 Yetunde reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
