Hi Berta, I am also researching the Pfeil family. I am curious about your Dr. Pfeil who came to America in 1840. Did he have any children? What else do you have on Dr.Pfeil? A first name? My gg-grandfather was Daniel Pfeil. I am looking for his parents and siblings. This line of Pfeils came to Baltimore then to Washington,DC and eventually to Colonial Beach,VA. Please respond.
