Lenis is of Greek origin and means "from Lemnos," an island in the Aegean Sea. It's a unisex name, though it's more commonly used for females. The name has been popularized by historical figures such as Lenis Pelopidas, an ancient Greek statesman and general from the city-state of Thebes. In some cultures, Lenis is also associated with the moon or the lunar cycle due to its connection to the Greek goddesses Selene and Luna.
The name Lenis experienced fluctuations in popularity throughout the period of 1917 to 1972, with peaks occurring in the late 1940s and early 1950s. The years with the highest number of births were 1942 and 1947, both having 9 births each. Despite these fluctuations, Lenis remained a relatively uncommon name throughout this period, as indicated by the total of only 170 births over four decades.
