Rosamaria is of Latin origin, derived from the feminine given name Rosa and the Latin word 'maria', meaning "sea" and "of the sea". This name has been used since medieval times in various European countries, including Spain and Italy, where it was popular among the nobility. The name Rosamaria was also used by Italian Renaissance poet Petrarch for his beloved Laura in his sonnets. Today, it is still a popular choice among parents who wish to give their daughters a name with Latin roots and a timeless elegance.
The name Rosamaria experienced significant fluctuations in popularity over the decades. It began with a low of just 5 births in 1944, then rose steadily to peak at 64 births in 1981. However, it has been on a general decline since the late 1980s, with only 16 births recorded in 2023, indicating that Rosamaria is now quite rare as a baby name.
