Some of Bernie Madoff's grandkids will be known by a different name: Morgan. Stephanie Madoff, who is married to Bernie's son Mark, went to court on Wednesday to legally change her last name and those of her two young children. She hopes her children will avoid the "embarrassment, harassment and endangerment associated with the name." Mark had no objections. Grandpa Bernie, who ripped off investors to the tune of billions of dollars, was sentenced to 150 years in prison.
