In the TV show "Criminal Minds", which features a group of criminal profilers, the team leader and his wife are expecting a baby boy and trying to decide on a name for him. The team lead is discussing the situation with his mentor, and notes that many times when they would consider a name, he would automatically link it to a serial killer: Jeffrey (Dahmer), Henry (Lee Lucas), etc.
In the end, they named the baby Jack. It was not mentioned whether the team lead was automatically put in mind of the Ripper.
The sad reality is that there are a lot of people who do terrible things, and as a consequence, it is very possible that ANY name could have a negative connotation attached to it. A few examples:
Edmund (Kemper)
Edward (Gein)
Robert (Hansen)
John (Wayne Gacy)
Peter (Sutcliffe)
Aileen (Wuornos)
Elizabeth (Wettlaufer)
Jane (Toppan)
Dorothy (Dorothea Puente)
and so forth.
