Funkhouser Family Genealogy Forum
I guess the next step is to see if the original German article can be found and find out what their sources are. Frieda Wilson in her book on the Christian Funkhouser family points out that there was a close relationship between the early Fleener and Funkhouser families in Southwest Virginia, an indication that there may have been a family tie there.
Christian Funkhouser came to the Shenandoah Valley of Virginia about 1736-7 and sometime in the mid 1740s married Christina Brock, daughter of Rudolph Brock (mentions his daughter, Christiana Funkhouser in his 1748 will) This family later went to Carolina and finally settled in Southwest Virginia. Two known sons, John and Christopher and a possible daughter or two- so there is certainly room in there for Sarah. Some additional supporting information such as name patterns in Fleenor Flener family, c-signing and witnessing each others documents would certainly be helpful.
