Two families are living through what feels like a TV show plot.

In fact, for Kevin McMahon, his life is like something pulled from Freeform series Switched at Birth after the 64-year-old says he discovered a hospital accidentally sent him home him home with the wrong family due to their identical last names. Now, he’s suing the hospital and opening up about the mix-up’s impact.

It began when members of Kevin’s family, as seen in a court summons obtained by NBC News, submitted their DNA for an Ancestry.com test and received results that they say indicated Kevin’s sister, Carol Vignola, had a brother by the name of Ross McMahon.

The document notes that after “doing some investigation,” Carol realized Kevin and Ross were born within two hours of each other on May 26, 1960, in Queens’ Jamaica Hospital Medical Center and that “the numbers on their birth certificates were consecutive.”

After telling Kevin what she’d learned, Kevin submitted his own DNA for testing and the “results did not reveal any relationship to his ‘sister,’ Carol Vignola, his niece nor anyone else he thought he was related to,” and instead identified a brother, Keith McMahon, whom Kevin didn’t know, per the filing.
