I think Emme and Maddie, but not Rosie - something I really dislike about it. Although, I love the sweet and simple Rose.
Rosalie/a isn't for me, I don't like many other Rose names at all.
Madelyn looks way too trendy, Madeleine would be gorgeous.
I love Emilia and it's my favourite of the names you have listed but as for your question I adore Emmeline - it's a new favourite of mine.
I love Rosalia, Rosalie, Madelyn, Emilia, and Emmeline/Emeline (only spelled those ways).
Emilia nn Emmy would be my favorite. Rosie would be a close second...I like Rosalie better than Rosalia. I'm not a fan of Maddie at all. I love the long versions of the name...but I really hate the nn Maddie.
