"Blend of Ella and Marie"
The name Ellamarie is commonly a female name from the "English" origin.
Ellamarie is a compound given name made from Ella and Marie, two given names long used in English and other European languages. The joined form first appears in United States birth records in 1921. It is best described as a combination of those two names rather than a name with a single documented root or meaning.
The pronunciation of Ellamarie is el-uh-muh-REE.
