(AP Photo/Dan Steinberg) (Newser) – Barry Williams, or as he’s better known, the guy who played Greg Brady, says his ex-girlfriend threatened to kill him, and herself, after losing a beauty contest in August. According to a restraining order Williams filed for in November, and spotted by TMZ, Elizabeth Kennedy accused Williams of having an affair, then ran into the kitchen and tried to grab a knife. Williams subdued her before she could harm anyone, but “I know that she will definitely try to harm me once she is aware that our relationship is now over,” he says in the document. He also accuses her of stealing his bank pin number and making off with $29,000. His bank has found security footage of Kennedy, and opened a fraud investigation.
