Heinly History states that Magdalena Hagenbuch, daughter of Michael was born on 9 Dec 1787 and died at age 85 years.
Enoch’s unabridged history states that she married Abraham Greenawald and had six children: Benjamin, Isaac, Jonathan, Rebecca, Lucinda, and Lydia. When Abraham died, she remarried—to Andrew Reichelderfer. They had one daughter, Lavinia. At 85 years, she died and she is buried in Paul’s churchyard, Lehigh County, PA.
The 1870 census shows a “M. Greenawald”, Female, Age 83, living in a household with Paul and Lucinda Meyerly near Weisenberg, PA. This is near St. Paul’s Church Cemetery, Seiberlingsville, Lehigh County, PA.
Since the age of 83 aligns with Enoch’s history, this is believed to be the Magdalena he describes.
