John (1576-1602) Barker, b. 1576 - d. 1602, is decidedly not the son of Richard Baker, of Dorchester, b. 1614 - d. 1689 and/or Faith Baker, b. 1616 - d. 1689. I have cut that relationship and thought I would post this message to let descendants know they might want to research the line a bit more.
Of course, since they were his only connection into the tree, he is now floating about aimlessly as driftwood. So that is extra reason to investigate him. :) If someone likes a good genealogical mystery, maybe you can help us find his rightful home.
