I'm sorry, but this isn't a name. It's just the first syllable of Jason. It even sounds incomplete. Frankly, I'm rather surprised at Jace's surge in popularity.
What the...? Why is this all of a sudden in the top 100? Is it because one of those horrible teen mom "stars" used it? It's an ok nickname for Jason, but it just doesn't sound right as a full name. It sounds very similar to the overly youthful and trendy chase, which isn't a very good thing. At least it's not another -aden name. But names that have rapid surges in popularity are usually not good choices.
