"Blend of Margaret and Ann"
The name Margaretann is commonly a female name.
Margaretann is a compound of the established names Margaret and Ann, joined into a single word without a space or hyphen. Both elements are long documented in English naming: Margaret goes back through Latin margarita to the Greek word for pearl, and Ann to the Hebrew Hannah. The joined form begins appearing in United States birth records in 1926.
The pronunciation of Margaretann is MAR-guh-rit-an.
