The theory that is always exccepted by all rseearchers that I have ever come in contact with is the following
"Daniel Dafoe of Vail, Switzerland as the head of the American Branch, arriving in 1710"
It appears that the family structure is fairly well supported back to Abraham. I have Conrad, son of John Ernst Dafoe and John, son of Abraham. Do you concur?
YES I CONCUR!!!!! it goes: Daniel, Abraham, John Ernst, Conrad, William, David Conrad, Victor, Luther, Me
Are you related ???
