Karriann is of American origin and means "song, melody". It is derived from the feminine given name Karen, which itself originates from the medieval name Caron, meaning "freeholder". Karriann was popular in the mid to late 20th century but has since become less common.
"Karriann saw a peak in popularity with eight births each in both 1971 and 1976, followed by five births in 1977, totaling twenty-one babies named Karriann over these three years."
