Cynthia is a classic feminine given name of Latin origin, derived from the Greek word "Kynthos," which means "from Mount Kynthos." This name was popularized during the Roman Empire and has been used widely throughout history. It gained popularity in English-speaking countries during the 19th century and reached its peak usage in the United States around the mid-20th century. Today, Cynthia is still considered a timeless and elegant choice for a girl's name.
Cynthis had a peak popularity in the mid-1960s with eight births recorded in 1963 and six births each in 1964 and 1965. There was a gap of two years before another birth was recorded in 1967, followed by fluctuating numbers up to 1973. After that, there was a significant decline with only five births in 1985 and six in 1989, bringing the total number of births to sixty over this period.
