YDNA test results, Dudley line <-> William Street line

John Street (Dudley line) to Ed Street (William Street line) YDNA MRCA results. My results: Y-111, His results: Y-12. I have contacted him about doing a possible upgrade to his kit. If we can do that we can put this parent's issue to bed once and for all. However, that being said the compare results yield that yes Dudley Street is the child of William Street Jr.. Confusion persists in the notion that Dudley street came directly from England, yet others insist Dudley street was a descendant of William Street. The line certainly has Williams, Francis, and Dudleys in their name indicating they are indeed in the Worcester line of Virginia Streets.
