Eudora is from the Greek eu (good) + dōron (gift). Eudora Welty (1909-2001) — the *American Southern Gothic novelist and short-story writer whose The Optimist's Daughter (1972) won the Pulitzer Prize. Her A Curtain of Green (1941), The Robber Bridegroom (1942), and The Golden Apples (1949) are foundational works of American short fiction. Photographer for the Works Progress Administration during the Depression — her portraits of Mississippi are now in the Smithsonian. First living author included in the Library of America series.*
Subject of Suzanne Marrs's Eudora Welty: A Biography (2005).
Eudora 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 Eudora reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
