Robert -- this is some very interesting information you've dug up. I only we could take it a litte further. As probably know, Francis Wright (1690) gets very little attention and his father (if William Wright is the right man) gets a short shift as well.
Have you ever found a definate link between William Wright and son Francis Wright (1690)?
I've also seen that Ralph Briggs and the Wright gang show up repeatedly on the thithables list.
Also wonder about Lydia Briggs. It appears she starts out with John Wright as her guardian, but shifts to Richard Parsons later. Her brother makes a move as well, which I suppose indicates the death of John Wright. Do you have a copy of his will you could share online??
