Thanks for your long and detailed reply. I fear I can't give much to you in response. On the Thomas Cooper marriage, I have no evidence - just a steal from (I suspect) the Leveritt tree on Genes Reunited. So your records may well be more authentic.
With regard to your lengthy discussion of missed burials, this isn't part of my tree, the last Thomas Cooper I have born in Henley is the 1626 one.
With regard to the Mary Turner/ John Earl/Thomas Earl conundrum, I have the same burial date for Thomas Earl, but have his age recorded as 86, which would give a birth year of 1745, making Mary only 49... Not impossible. Stretching probability, but no more than that.
Thanks for the info on John Green - that makes me more confident.

If you're still awake after all that, maybe you could proffer any comments?
Oh and there's another strand which goes via the Ferrers/Despenser route to Edward the First, and another that goes via the la Zouche/Fergent/de Bretagne/Vermandois/Pepins route to Charlemagne.
