Is Ann Coulter Jewish?

Many people wonder if Ann Coulter is Jewish. People think this because her maternal grandfather's original surname, Weissinger (Ann's grandfather changed his name from Hunter Hart Weissinger to Hunter Hart Martin), sounds similar to other names which are commonplace amongst Jewish families. Indeed typical western Jewish names like Weisz and Weisbom are actually derived from Weissinger. Ann Coulter is not Jewish and the name Weissinger is simply an old Germanic word used to describe people with white hair and/or pale skin.
