I personally would never use a name if it had a very strong association, regardless of whether it was a good or a bad one. I would never name a child Luther because regardless of whether Martin Luther King Jr. was my greatest role model or not, the name Luther just immediately draws attention to him. For example, one may love Miley Cyrus but would never want to name her child Miley because there is just such a strong association with that name, and even if she loves Miley Cyrus, the name will always have the association which can be annoying at times, despite whether it is a good or bad association.
