Dexter

Centuries ago, Dexter was someone who dyed clothing; on TV, Dexter took care of a different kind of dying, namely murdering people as a serial killer on the eponymous series. The Latin name, however, referred to someone who was right-handed, therefore believed to be dexterous and skilled. While the name has fluctuated in the charts for centuries, Dexter always seems to hang around. It has also hit a high note with singers: Elvis Costello and Diana Krall named one of their twin boys Dexter in 2006, and Charlotte Church named her son Dexter in 2009.
