Thank you, John. I am aware of "Stemmata Shirleiana" but have only read excerpts online. In my area I don't think the book is readily available. Does Stemmata S. contain any conclusive evidence about the relationship of Saswallo (or Sasuualo, etc.) to the Sewell/Sewall family? It's interesting that you say your Mother used to refer to a "connection" with Lord Ferrers; maybe you should not dismiss it too casually, unless, of course, you are also aware that notion was originally concocted by someone prone to delusion!

I wonder if the current fad of DNA testing might reveal anything interesting? I notice on the Shirley website that they are pursuing testing.

Sincerely,
David
