"The name Rosalio was quite popular in the early to mid-20th century, with over 2000 babies given this name between 1911 and 2023. The peak of its popularity occurred around the late 1920s to early 1930s, with consistent high numbers until the late 1950s. However, starting from the 1960s, the usage began to decline steadily, reaching a low point in recent years with only single-digit births per year since 2014."
