A quick timeline from the changes and a note from another discussion I've had on this:
9 Mar 2011 - merged - father appears as Thomas Dudley-129 (Governor mentioned earlier), mother Dorothy Dudley (Yorke-44).
17 Jan 2013 - merged - no change in parents
24 Jul 2013 - merged - no change in parents
23 Mar 2014 - message "this person can not be the child of Yorke-44 who was born three years after him"
1 Apr 2014 - message "... I believe his father is listed incorrectly as Thomas Dudley. His father and mother should be Roger Dudley and Susannah Thorne and Thomas is actually his older brother. My basis for this is that they are only three years apart in age and both Thomas and Roger have wikipedia entries, where Roger has a younger son named David."
22 Jul 2014 - merged - no change in parents
25 Jul 2014 - removed the mother, removed the father, edited bio to read "proposed parents (at Ancestry.com and other user generated online sources) are impossible due to ages. His parents were NOT Thomas Dudley and Dorothy (Yorke) Dudley."
16 Aug 2014 - new (current) mother and father added. The old father, Thomas Dudley-129 has now become a brother.
4 Mar 2015 - in discussing addition of new parents with provider of information, confirmed the source was wikipedia with a note saying "and the fact that David was already present on wikitree as a relative of Thomas Dudley (meaning someone had made the connection previously though we don't know on what basis)"
