Well, while to other people the name is reminiscent of "epi pen" or a dog name, or a mispronunciation of the nickname Abby, to me it makes me think of a Scottish ballad titled "Eppie Morrie". In it, Eppie is clearly a strong individual as she resists a forced marriage and returns home safely, free to do as she will with her life (at least in some versions). I think of a brave individual and not of a dog when I hear the name.
Silas Marner is one of my favorite books. It is filled with hope, and shows how the love of child can change one's life for the better. Whenever I hear the name Eppie, I think of a little golden-haired child full of hope and joy.
Awful. Sounds extremely immature and quite embarrassing even as a nickname. How could any woman called Eppie be taken seriously? Sounds more like a name for a dog.
As someone who is called Eppie I have to say I like it although it does draw questions when I introduce myself. Some people do think you are trying to say Abby, and it is often misspelt but on the whole I think it is sweet name.
