I've actually always resented my parents for giving me a common name -- Maria. (The year that Carlos Santana's "Maria Maria" came out was a disaster.) I go by Mia, now, and am hoping to change it legally in a few years, once I've settled into my married last name.
Anyway, on the "horrible names" front, one of my cousins is named Justus (pronounced Justice, except my grandparents usually call him Eustice.) His parents find it amusing that every time he eats "Justus is served." Justus's little brother is named Dante'. I asked my aunt why the apostrophe was there, and she just said it "looked nice."
On the other side fo the family, parents Jay and Teresa named one of their sons Jayson, another Terrence, and their little girl is named Jareesa.
