Penelope is an unlikely 21st century baby name success story. Off the Top 1000 for 25 years, Penelope jumped back on in 2001 and has been heading uphill ever since, propelled by the trend for mythological names, Spanish actress Penelope Cruz, and some high-profile celebrity babies.

Well-established Irish and Scottish name that has never really caught on across the pond. Remembered by an older generation as the beautiful red-haired ballerina in the film The Red Shoes, Moira Shearer.

This is the original, more prosaic spelling, but the airier Claire now dominates.
