Marili is a feminine given name of Latin origin, derived from the Roman family name Marilius, which was itself derived from the Latin word "marius," meaning "of Mars." Mars was the ancient Roman god of war, and his name is believed to have been associated with the month March, when military campaigns typically began in ancient Rome. In some instances, Marili may also be considered a variant spelling of the name Marilyn, which is of English origin and means "little rebel" or "song of the sea." The name Marili has gained popularity as a given name for females in various countries, particularly those with strong Roman Catholic influences. It is often spelled with an 'i' at the end to create a unique and memorable sound, despite being derived from names that typically end with '-us' or '-n.'
The name Marili experienced varying popularity over the years, with a notable peak of 20 births in 1996 and another high of 14 births each in 2005 and 2008.
