Jon Garth Murray (November 16, 1954 – September 29, 1995) was the second son of late controversial activist Madalyn Murray O'Hair, the first president and founder of American Atheists, Inc., in 1963. He was also the half-brother of the reverend William "Bill" Murray.
Murray's father had children with different women throughout his life.
It was mentioned that Murray had a half brother, so his father HAD to have relations with different women. I think the statement was a little too abstract for the system.
