I love
Evangeline!
I knew a girl who was named
Evangeline and went by
Gina. I think she goes by
Lena now though.
As for the sister set I think it depends on how you pronounce each name. If you are usin the leen ending for both or the lien ending for both it might be too similar. If you are planning on using a nickname for
Evangeline then i wouldn't worry about it. Both names are beautiful.
How are you pronouncing
Evangeline and
Adeline?
