From the experts:
One-time overnight success name, thanks to Hannah Montana actress and singer Miley Cyrus, Miley has fallen quickly from her peak of Number 127 in 2008. For Miley Cyrus, Miley was a childhood nickname (because she was so smiley); Destiny is her real name. Miley is a good lesson in avoiding trendy names. Popular opinion of the source can sour leaving a fresh name looking dated.
