Seems quite a split on here then!
I did wonder if people felt Emma too safe or plain....as have wondered myself. But I love the classic simplicity of it, and feel it's pretty without being frilly, and strong. There are many Emmas of my generation (mid thirties) but I don't know any babies or children with the name. I do know a baby and a child called Martha though. It seems Emma was overdone in the 70s/early 80s and then faded a little as Emily, Amelia etc came to the fore?
I do appreciate others may have negative associations with Martha (biblical/literary), but I don't have them myself so not sure that would put me off. As with Emma I do like that it's fairly simple but (to me anyway!) quite a strong name. And as someone commented above (sorry typing on my phone so can't scroll), there are so many Ellies, Millys and Tillys where we are, I quite like the idea of something different.
Will have to mull it over some more, but I do appreciate all comments in the meantime 
I also still love Annabel/Annabelle, and think DH likes it but not sure he LOVES it, whereas it was DH who suggested Martha last night.....
