Wenona (also Winona) is a Dakota/Lakota Sioux name traditionally given to the first-born daughter. It means "first-born daughter." Winona Ryder (born 1971), the American actress, was named for the city of Winona, Minnesota.
Wenona is rising as Indigenous naming traditions are revived.
Wenona 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 Wenona reduce to 9, The Giver. This is a traditional interpretive system, not a factual claim about the name.
