Theodosia first appears in the Social Security records in 1880, when 10 girls received the name. Its peak came in 1918, when 45 girls were named Theodosia — good for #1091 that year. Today's parents encounter it as a name from their grandparents’ generation, which is precisely the vintage window from which names get revived. Following the curve matters more than today's snapshot: a name's position on its rise-peak-decline arc is the best predictor of how common it will feel in a kindergarten class five years from now.
