"Blend of Ella and Mae"
The name Ellamae is commonly a female name from the "English" origin.
Ellamae is a compound of the given names Ella and Mae, written as a single word with no space or hyphen. Both are long-established English-language given names, and the joined form carries no meaning of its own beyond them. It first appears in United States birth records in 1898.
The pronunciation of Ellamae is EL-uh-may.
