"Blend of Eva and Lena"
The name Evalena is commonly a female name from the "English" origin.
Evalena reads as a compound of two established girls' names, Eva and Lena, written as a single word. Eva is the Latin and English form of Eve, and Lena is used both as a short form of Elena or Magdalena and as an independent name in its own right. The combined form appears in United States birth records from 1880, in the period when such joined double names were being registered.
The pronunciation of Evalena is ev-uh-LEE-nuh.
