The name gained prominence during the Middle Ages and has since been used in various forms across cultures. Notable bearers include Ruth Bader Ginsburg, an Associate Justice of the U.S. Supreme Court, and Ruth Wilson, an English actress known for her role in the television series 'The Affair'.
"RutherAnn appears to have been a popular name among parents at the turn of the century, with a notable peak in popularity during the early 20s, reaching its highest point in 1923 with 23 births. However, this popularity was short-lived and declined steadily throughout the subsequent decades."
