I really like the name Emmeline... but in my head I always pronounce it Em-eh-lyn rather than Em-eh-LEEN, and I much prefer my (I assume incorrect!) pronunciation!
I'm not sure if this is partly accent - I'm west coast Scottish, and have a cousin Jacqueline who is sometimes referred to by various family members phonetically as Jacklyn, though I know Jack-eh-LEEN is correct.
How would you pronounce Emmeline? I don't really want to do a weird spelling variation - I know Emmelyn would be more obvious, but I think it is a bit of an invented spelling which puts me off!
I also thought of Evelyn and Emily - but don't love either quite as much.
