Carloyn is a unique and modern-sounding female given name of uncertain origin. It could possibly derive from the Italian name Carlo, which means "freeholder" or "strong," combined with the English feminine suffix -yn. Alternatively, it might be a variant spelling of Carolynn, a name that combines the classical name Carol with the feminine suffix -ynn. Regardless of its etymology, Carloyn is a contemporary choice for parents seeking an uncommon yet appealing name for their daughter.
Carloyn was a moderately popular name from the late 1940s to the mid-1970s, with some fluctuations in popularity over the years. The name peaked in popularity during two periods, first in the early 1950s (with 13 births in both 1952 and 1953) and again in the late 1960s to early 1970s (with peaks of 13 births in 1970). However, the name's popularity decreased significantly after 1984, with only five births recorded that year. Overall, Carloyn was a somewhat uncommon name, with a total of 248 births over this period.
