Emmeline is all the rage right now online, popular with pretty much everyone, and it is easy to see why. It is familiar like Emma and Emily, currently two of the most popular names, and Emmeline is a little unique, mysterious and alluring, and rare enough that you think you've heard it before, but haven't. In fact, in 2010 there were 140 baby girls named Emmeline. It was also popular in medieval times.
Other variants and names that are very similar are as follows: 13 Emalina, 40 Emaline, 117 Emalyn, 6 Emalyne, 40 Emalynn, 36 Emelin, 35 Emelina, 75 Emeline, 98 Emelyn, 5 Emelyne, 9 Emelynn, 11 Emilene, 10 Emilina, 10 Emiline, 73 Emilyn, 5 Emmalena, 15 Emmalene, 75 Emmalin, 76 Emmalina, 203 Emmaline, 370 Emmalyn, 14 Emmalyne, 215 Emmalynn, 19 Emmalynne, 6 Emmelin, 13 Emmelina, 140 Emmeline, 21 Emmelyn.
It is hard to tell if the names listed above are true variants of Emmeline or if they are variations of Emma or Emily. All of these versions considered, I would not call Emmeline "rare" anymore.
Emmeline is Old French from Old German, Ameline from Amal, meaning "(to) work," "industrious," or "hard worker." It is from the same root as Amelia. However, as a variant of Emma it means "whole, entire, universal."
