Guinevere is the Norman French form of the Welsh Gwenhwyfar, which is usually explained as "white phantom" or "fair one"; Jennifer is the Cornish version of the same name. It belongs to King Arthur's queen in the medieval romances, which gives it a legendary, storybook grandeur. Guinevere climbed from number 1350 in 2015 to the top 1000 in 2024 and reached number 899 in 2025, its best rank ever.
