Kay, I descend from Johann Jakob Brake who lived in Virginia. He returned to Germany, but his family remained in what is now West Virginia. Up until a decade or so ago, the thought was that he descended from the Dietrich and Douglas ancestors to whom you refer. This has been soundly disproved. If you go to
www.perrybrake.com/BrakeLinie.html, I posted evidence that he was born "Jakob Brechtel" in Durlach (a suburb of Karlsruhe) in southern Germany. I am confident the same Dietrich/Douglas couple are not in the North Carolina Brake past, also. A Brake descendant paid a German researcher to look for the ancestral line. That so-called researcher fabricated the information. Some speculate that NC Jacob and VA Johann were brothers, but nobody has come up with evidence as far as I know. In the second paragraph of the web page cited above, you can find a link to a huge files on the NC Brake line.
