"Blend of Emma and Jean"
The name Emmajean is commonly a female name from the "English" origin.
Emmajean is a compound given name formed by joining two established names, Emma and Jean. Emma is a Germanic name in long use in England, and Jean is the French form of John that also entered English feminine use. The joined form appears in United States birth records from 1917, and the two-name pattern places it among the hyphen-free feminine compounds recorded in American naming of that period.
The pronunciation of Emmajean is EM-uh-jeen.
