Marsi is a feminine given name of Latin origin, derived from the Roman family name Marsus, which was believed to be connected to the god Mars. It signifies a person who belongs to the Mars family or has connections to the city of Marsi, an ancient region in central Italy. In some cultures, Marsi is considered a variant spelling of the more common Marsha, which also shares Latin roots but has gained greater popularity as a standalone name.
"Marsi experienced peaks in popularity in the late 1960s and early 1970s, with 13 births in 1968 and 10 births each in 1971 and 1972."
