You're absolutely right about the tortuous confusion.
The Tyldens you list appear to be from Kent County, England, not Kent County, MD, though every TILDEN researcher believes the families are one in the same. Milsted Manor was an ancestral home to Tyldens (see
http://www.google.com/search?num=100&hl=en&newwindow... )
The family on both sides of the Atlantic showed a fanatic propensity to perpetuate the names, John, Charles, Thomas and Marmaduke, though I will say the Marmaduke moniker seems to be limited to the Maryland members, not the Situate, MA, members.
The names you mentioned don't ring an immediate bell with me, but I'm always interested in contemporaneous primary-source material about Tildens/Tyldens. Can you share more, either on-line or off?
