I no longer believe that Apollonia Bacher is my 5th Great-Grandmother.
Research has revealed that she married Michael Reiser in 1754 at Ebenezer, Effingham County, GA and bore seven children, Nathaniel Reiser, Israel Reiser, Hannah Elizabeth Reiser, Catherine Reiser, Maria Reiser, David Reiser and Christine Reiser.
Further, Hans Ulric Gyger did not migrate to GA until 1767 when he received a Royal Land Grant "across the Great Ogeechee." His application states that he has a wife, four children, and one Negro.
These conflicts make me think that my g-grandmother is another Apollonia.
