This research homepage details my paternal grandmother's lineage back into North Carolina. It is thought that the Shook family is Pennsylvania Dutch, originating from Germany in the 18th century. Hanson Shook's parents were probably immigrants, given that he spoke German. Shook is probably an Americanized spelling of the German surname Schuck.
The Pennsylvania Dutch are the descendants of Germanic peoples who emigrated to the U.S. (primarily to Pennsylvania), from Southwestern Germany and Switzerland. The origin of the word 'Dutch' is a "folk-rendering" of the Pennsylvania Dutch's own self-designation Deitsch. It corresponds to German Deutsch and indeed the Pennsylvania Dutch come mostly from what is now Germany rather than the Netherlands. Logically, their language too is ultimately a derivative of Palatinate German, not Dutch.
I think that it is likely that my Shook line is related to another line of Pennsylvania Dutch Shook's who also settled in North Carolina. They are chronicled on this website, but I have yet to discover a link.
Dr. Edwin Martin Shook (b. 1911) was an archeologist who studied Mayan ruins and was featured in Life Magazine and National Geographic.
