Marilisa is of Italian origin and means "bitter sea." This name has gained popularity globally due to its unique sound and appealing rhythm. It consists of two distinct parts: Marili, which is believed to derive from the Italian name Margherita meaning "daisy," and sa, a suffix of Italian origin often used in female names. The name Marilisa is not tied to any specific saint or figure, making it independent of religious influence.
The name Marilisa experienced a peak in popularity during the late 1960s and early 1970s with five births recorded each year between 1965 and 1971, totaling twenty births in this period alone. After a decline in popularity through the 80s and 90s, it saw a resurgence at the turn of the century with six births recorded in both 2000 and 2007. Over the entire span of these statistics, from 1961 to 2007, there were fifty Marilisa births recorded in total.
