Everyone has an anthroponym, but that's okay. It's just a big word for your name. The problem is how they come and go out of style. I recall hearing about someone naming their baby Layla around 1971 and even then I felt for the child, because she'd never be able to hide her age. The same for Shania and Daenerys. Silly me, although my name is not that common, even I have a name that came and went and only belongs to women my age (people just don't name their daughters "Miss" anymore). Dr. Erica Brozovsky (previously at Neatorama) explains why names become fashionable and then not. Both my daughters unintentionally ended up with very common names for their age group, even though I decided on a name for my youngest 30 years earlier. But hey, in 100 years or so, your anthroponym may come back into style! I personally know a family with a newborn named Mabel, and it seems perfect for her.
