"Blend of Cheryl and Ann"
The name Cherylann is commonly a female name from the "English" origin.
Cherylann is a twentieth-century English compound of the given names Cheryl and Ann, written as a single word without a space or hyphen. Cheryl is itself a modern name that entered use in the early 1900s, and Ann is the English form of Anna. The joined form Cherylann appears in United States birth records from 1944, which fits a compound created in the first half of the twentieth century rather than an inherited traditional name.
The pronunciation of Cherylann is SHER-uhl-an.
