Your classic choices, while pretty, are super popular. Not only will she be one of many Emmas but she will also have the same middle names as most of the girls. The only ones that may be an exception are
Emma Autumn and
Emma Alice. Personally, I would branch out to something just as pretty and classic/classic looking but less common like:
Emma IsadoraEmma Coraline
Emma JosephineEmma AvelineEmma AdelineEmma JulietEmma LaviniaEmma Lenore
If you want to go with what you already have, I would go with
Emma Alice. If you want something similar but less common I would go with
Emma Elspeth,
Emma Charlotta,
Emma Autumna (sorry, I dislike double middle names, especially when one is filler),
Emma Caterina /
Catherina, or
Emma Lillie /
Lillian /
Lilith. If you must go with double barreled, I think
Emma Lilith Rosalind would be a good choice to add your
Lily and
Rose preferences without being super florally and common.
Or maybe, change
Emma to the following options but keep the middle names? That would allow a longer name with the nn
Emma so that when you are in a crowd of kids instead of yelling
Emma and having 4 girls come running, you can shout her full name and just get one response.
Emmalina
EmmalineEmelise
EmeliaEmilianaEmilieEmina...and if you are feeling super adventurous,
Emerald.
