A strong, straightforward Irish unisex surname, with a merry glint in its eye, Reagan has been leaping up the popularity lists, to become one of the top girl names starting with R. Some will inevitably link it to President Ronald, but spell it Regan and it's a Shakespearean name: a daughter of King Lear.

Originally an English surname, borrowed from the place name, Kendale, Kendall was given almost exclusively to boys until the 40s when it began to be used for a small number of girls each year.

St. Landry was a seventh century bishop of Paris, founder of the city's first hospital, though in the US, it may be better connected with legendary Dallas Cowboys coach Tom Landry, an association that makes this a sports hero name with a hint of ruggedness. Familiar in France between the 1970s and 2000s, it also featured at the latter end of the US Top 1000 during the 20210s.

This unusual name from the Nahuatl or Aztec language has one of the best meanings around. It sprang onto the US popularity list in 2006 and made a brief appearance in the Top 300 before sliding down a bit.

Italian names like Gianna, Giovanna, Ginevra, Giulia, and Giuliana are being used increasingly by trendy baby namers — whether they have Italian roots or not.
