"Blend of Carol and -een"
The name Caroleen is commonly a female name from the "English" origin.
Caroleen is formed from Carol with the -een ending, the same feminine ending that appears in Colleen, Eileen, Kathleen and Maureen; that ending goes back to the Irish diminutive suffix -in. It is a different formation from Caroline, which ends in -ine and carries the stress on the first syllable. No independent meaning is recorded for Caroleen itself.
The pronunciation of Caroleen is KAR-uh-leen.
