"Blend of Shirley and Ann"
The name Shirleyann is commonly a female name from the "English" origin.
Shirleyann is a compound given name made by joining Shirley and Ann into one word. Shirley is an English name, and Ann is a form of Anne, so the joined name carries no meaning beyond the two names it is built from. The single-word spelling appears in United States birth records from the 1920s, which fits a twentieth-century American formation rather than an older tradition.
The pronunciation of Shirleyann is SHUR-lee-ann.
