Like I mentioned, I'm not related to this person and haven't researched him personally, but I don't think having 16 children would have been newsworthy enough for a Missouri newspaper to pick up a story from Virginia!
Someone else sent me this: "Stories were told that during Owen's lifetime, he had 44 mistresses and was the father of 108 children. He was known as "Owen of All". Rumor also has it that there is a book titled "The Life and Legend of Owen of All"."
Between the mistresses and multiple wives, I wonder if HE even knew how many children he'd fathered!!
