Well, this is the right place for what you are looking for. Just go to The Lester S. Levy Sheet Music Site, type evelina in the search box, and the sheet music will come up. I thought we had a discussion of the song fairly recently, but it must not have been part of the thread title, because I can't find it. It was published in 1863, but the sheet music listed the authors as Words by M and Music by T. ?????

I do remember it coming up in the old time music news group. I'll look there and see if I can find it.

There have been numerous earlier recordings as well, right offhand I can name LuluBelle and Scotty, and The Blue Sky Boys. Like any other song, people adapt it to their own arrangements. I have also heard it pronounced both ways.
