Have been looking for the lost "Pfeil's" for about 13 years.I have a Catherine Pfeil who was married to Daniel Pfeil. Both Born in Germany according to census records. They lived in Washington, DC and bought a farm in VA which they developed and called it the Colonial Beach Development Corp. He sold shares of land to a lot of family (more Pfeils). Catherine died some time in the late 1890's (she disapeared from the transactions on the courthouse books) and Daniel I believe took a new wife and partner in the corporation. Don't know where she was buried or exact date of death. If I can help you in the MD, DC, VA area please respond.
