The possible Canadian offspring of JFK was never brought up with Madaleine Brown because no one knew of this story until recently and well after her
I have looked into this man's allegations and concluded that, even if there was something there, it will be suppressed and go nowhere. The key point
is that a DNA test failed to prove any relationship with JFK. Check out the lengthy article in Vanity Fair. Furthermore Jack Worthington Jr.'s family
all deny any such relationship, including his mother, who would be the most closely connected.
I'm afraid this story is a non-starter.
