From the Roman name, Aemilia, latin word aemulus meaning rival. Industrious, hard-working, stubborn, obstinate.
When I first looked up my given name, I found something similar to the etymology and list of adjectives above. Yet, none of these explained why my parents decided to name me Emily. After all, they had no way of knowing that this ugly, squalling baby would be a diligent worker, at all stubborn, or competitive in any way. (I assert that I am some, if not all of these things at times.) So, I was named after my great-grandmother whom I never knew. My mother was close with her despite speaking no Italian — my great-grandmother was from Sicily — and my great-grandmother speaking little to no English.
