Lonni is a unique and charming name of Scandinavian origin, predominantly used in Sweden. It's derived from the old Norse word "Lónn," which translates to "wave." This elegant moniker embodies fluidity and grace, much like the ocean tides it's named after. Lonni was traditionally more popular among boys during its heyday but has recently seen a resurgence in popularity for both sexes, adding to its versatility. It is often paired with the Swedish surname "Björk," meaning birch tree, creating a harmonious blend of nature-inspired names.
Lonni is quite popular with parents in those years, though it seems to have faded from popularity after 1965.
