Aunt Barbara is the aunt of Howard Wolowitz and may be the sister of either Sam Wolowitz or Debbie Wolowitz, though probably hers since she is divorced. At her house, Howard lost his virginity to his second cousin Jeanie in a Toyota Corolla after his Uncle Murray Wolowitz's funeral. She has become an aunt-in-law to Bernadette Rostenkowski-Wolowitz since her marriage to her nephew Howard. She is the great-aunt of Howard and Bernadette's daughter, Halley Wolowitz.
