I have an Anna Christina Feiser, born 1 May 1749 in Dover, York County, Pennsylvania. Her older brother, Peter Feiser was born in December of 1743 in Borob, Hachenburg Province, Germany. Christina married on 27 July 1756 to Erasmus Rosenberger. She died in 1771. Anna Christina and Peter were the only two children of Johnnese (John) Methias Feiser, born 30 November 1716 in Borob (Borot), Hachenburg Province, Germany and died 14 May 1781 in Dover Twp, York County, Pennsylvania. Johnnese had married in August 1743 to Christina Schneider who was born 1720 in Borob and died August 1753 in York County, Pennsylvania. Johnnese married (second) in September of 1753 to Elizabeth Schlatter born 17 August 1723 in Hohmannthal, Switzerland and died 12 April 1800 in Dover, York County, Pennsylvania. They had 8 more children. I am not aware of Christina marrying a Baumgardner. Could Baumgardner actually be Rosenberger? Hope this answers some questions for you!
