Wynonna is from the Dakota (Sioux) winuna — the traditional name given to a first-born daughter (also spelled Winona or Winnona). Five Grammy Awards as half of The Judds. The Judds were inducted into the Country Music Hall of Fame on May 1, 2022 — one day after Naomi Judd died by suicide on April 30. Wynonna's solo career has produced four #1 country albums and 20 top-10 singles.
Wynonna 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 Wynonna reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
