An "old-man" nickname for girls, Lennie could feel as fresh as Billie, Scottie, and Stevie — and if the 100 Year Rule is anything to go by, it may well be time for it to come back round, having been a US favorite in the early 20th-century. Cutesy but solid, it is sometimes used as a feminine form of Leonard, however, other sources include Eleanor, Ellen, Helen, Helena, Magdalena, Lennon, Lennox, and Gwendolen. 
 
If Lennie feels too Of Mice and Men for you, there's the pan-European Leni to consider too — identical in sound but lighter and fresher in appearance. In fact, it's a charting option in Austria, Germany, and England and Wales.
 
Lennie ranked just outside the England and Wales Top 1000 in a recent year, given to 27 girls (making it as popular as Cerys, Dotty, Marceline, and Saffron in the same year), while in the US it was chosen for 69 girls — the largest number of female Lennies born in a single year since the 1920s.
