Many people, including myself, have incorrectly identifed Margaret, wife of Michael Hoyle, as being the daughter of Johann Philipp Dellinger and Anna Maria Brandstätter. It appears that the root of this connection first started in L.M. Hoffman's genealogical work that he published as "Our Kin" in 1915.  However in the Oberacker book by Herzog and Meyer, there is no mention of this daughter. There is mention of a daughter Margaretha who was born on 6 January 1750. However this Margaretha cannot be the same person as the wife of Michael Hoyle because Michael Hoyle and his wife Margaret had several children by the early 1760s. Ten to 13 year old girls, even in the Carolina back country in 1760 are not typically having children. Another daughter of Johann Philipp Dellinger and his wife Anna Maria Brandstatter who possibly could be confused for the wife of Michael Hoyle is Catherina Margaretha Dellinger who was born 20 Aug. 1733, however she died the following year on 5 Jan. 1734.  With the exception of Hoffmans' book, there doesn't seem to be any evidence that supports that the Margaret who married Michael Hoyle was a Dellinger.  The information I have shows that Margaret, wife of Michael Hoyle, was born 27 Feb. 1745.
