I have a copy of a very old family tree (compiled in 1856-7) which claims "the common ancestors both thought to have been born abt 1580" ... however I have doubts about that, since their first child wasn't born until 1633. Most of the other births etc., seem ridgy-didge, but I haven't added them to my tree yet, and probably won't, until I find corroborating evidence.
More research required, I think ... *sigh!*
