I find the whole issue fascinating & wish I had the time and wherewithal to be a serious genealogist. My interests are mainly in linguistics, which I find quite helpful in understanding how fluid and flexible words and names really are. For instance, although I don't know much about the Lyndes, the Lyrados or the Dynleys...I can see just from looking at it, that they are easily confused, and perhaps, interechangeable, words. A census-taker could have written Lynde, and it looked like Lyrado, or a dyslectic might write Lynde for Dynle(y). Who knows? I would think to consider it though.
Regarding Matthew, and to whom he is connected in England... Has anyone yet found the document that would prove who his father is? For the Marmadukes, down in old Virginny, the connection seems most natural, as their name and station would attest. Connecticut is a different matter, granted, but one might expect that they had some connection to those around them...whatever that might be.
My sense, in reading Paul's book, is that he is not intentionally trying to mislead anyone, and Lord knows, he didn't have the Internet and computers to draw upon...which make access to information...and the compilation, typesetting, printing, and binding...a good deal easier. Even with the errors, it is a formidable work of great love, and I am, personally, glad for its existence. He would have a field day on the net!
As a left-hander, it is almost impossible for me to work linearly. Most lefties share this problem. Instead, my own approach is more holistic, intuitive, and subtractive. I will pursue all veins...as far as I can trace them, finding them more interesting than dead-ends...and strangely, at times, I run into other lines, which make the first line unnecessary, in a certain sense. Supererogatory.
Back to Matthew. It may well turn out that there are no remaining official documents which tie Matthew to Marmaduke...but the search ought not stop there. The connection might be in the form of family names, books, heirlooms or whatnot. Surely he didn't just spring up out of the slime.
I'd love to see a list of proofs and disproofs. Life would be much simpler...
