Lavinia

The name Lavinia has several possible etymologies. One theory suggests that it is derived from the Latin word “lavare,” which means “to wash.” Another theory suggests that it is derived from the Etruscan word “lau,” which means “daylight.” Yet another theory suggests that it is derived from the Sabine word “lahin,” which means “maiden”.

I think it's not meaning of Lavinia is purity. It maybe derived from the Latin word lavo which means "wash". In Italian word lavare means "to wash".

Lavinia could mean "purity" in Latin. It's a gorgeous name.
