I think it's certainly possible, but like
Serafina Starstrider said, a name is far more likely to be ruined by a terrible person you've actually met. Off the top of my head, disliked celebrities haven't ruined names I liked beforehand, but some names that have been ruined from real-life associations:
ConnorMarissaWyattJaredStephanie (nearly every
Stephanie I've met has been, to put it mildly, crazy)
