I am posting some correspondence with a Paul Wright who is interested in the link between PRA groups 5&14 and the Radclyffes. Since FTDNA has a sale for upgrades of DNA tests I wanted to point out that this would be a good time for those of you with close matches who would like to refine your knowledge of the time to common ancestor. going from 25 to 37 or 37 to 67 markers is probably more helpful than deep ancestry SNP tests. This does not always produce any more information but in some cases it is helpful. We are getting some very interesting information which seems to nail down the sequence for group 3 that hails from Bucks Co PA with clear matches in the Furness region of Lancashire. This fits with descent from Paul of Sunbrick Lancashire c1627. Here is the correspondence (starting at the bottom of the page).
Thank you for your very interesting email. I have little time to do such an analysis at the moment but I think I agree with your conclusions. Would you mind if I post this to the Pennington Rootsweb list or just our internal PRA roots web list? This might get more Pe(i)nningtons to go to 67 markers as there is a sale on at the moment.
One in this group (PRA groups 5 and 14) has taken a deep SNP test his result is:
M126- M153- M160- M173+ M18- M207+ M222- M269+ M343+ M37- M65- M73- P107-
P25+ P66- SRY2627- U106+ U152- U198-
he is U106+ as you suggested but we have several that are even closer to Radcliffes than he is, so you never know. Nick
