The story
Arleth is a variant of Arlette in use in Latin America, and Arlette is the French form of Herleva, possibly built from Old German words for army and legacy. History remembers a Herleva well: by tradition a commoner, and the mother of William the Conqueror. So a name with a conqueror's mother in its family tree now does its living in Spanish. The American record dates that second life precisely: 175 girls in the 1990s, 1,709 in the 2000s, 1,626 in the 2010s, and 3,330 so far in this one. The path itself is the story: Old German to Norman France to Latin America to an American certificate, four languages deep, and the name arrives at the door sounding effortlessly current.

Not on the record in England and Wales, Canada, Ireland, New Zealand, Scotland and Poland: those registries withhold small counts, so rare uses may sit below their floors.
Not on the Montevideo record for 1940 to 2011: that registry withholds nothing, so this spelling was not given there in those years. Not on the France record: nametree keeps spellings that reached 20 births in some year, so rarer uses are not shown. Not on the South Australia record for 1944 to 2017: that registry withholds nothing, so this spelling was not given there in those years. Not on the Austria record for 1984 to 2025: Statistik Austria publishes every first name down to a single birth, so this name was not given there in those years (before 2010 the record covers babies with Austrian citizenship only). Not on Norway’s list: Statistics Norway lists only first names carried by 200 or more living people, so rarer names are not shown.
