Besides infamy, you would have to look at what made a name popular in the first place. When that source is no longer in the public eye, it basically becomes forgotten (except by diehard fans).
As names
ascend in popularity, this necessarily forces others down on the list. Besides individual names, there are
groups of similar sounding names that may ascend or descend, as well (in a euphonic naming society).
"Like arrows in the hands of a warrior are sons born in one's youth." Ps. 127:4
