"Blend of Kimberly and Ann"
The name Kimberlyann is commonly a female name from the "English" origin.
Kimberlyann is a two-name combination written as one word, joining Kimberly and Ann. Kimberly is an English given name, and Ann is an established English name that comes through Latin and Greek from Hebrew Hannah. The joined form is recorded in US birth records from 1962, which is consistent with the period when the separate name Kimberly was in wide use; the combined spelling has no meaning of its own beyond its two parts.
The pronunciation of Kimberlyann is KIM-ber-lee-ann.
