My grandmother, Magdalena Doerr, came to U.S. in 1909,she was descended from the Doerr line as follows: Magdalena Doerr b. 1887 Kassel, Russia d/oFriedrich Doerr b. 1851 Kassel, Russia s/oGeorg Doerr Jr, b 1819 Kassel Russia s/oJohann Georg Doerr, b. 1791 Offenbach, Germany md. Anna BARBARA Grosshans, b.1794 Godramstein, Germany s/oJohann RUDOLF Doerr, b 1757 Offenbach, Germany md Maria Clara Permann s/oJohann Michael Doerr, b 1727 Offenbach md Anna Maria Bertolff s/oValentine Doerr, b. 1682 _________, d. 1749 Offenbach, Germany
Since your line is from Offenbach,I'm hoping this is the same family.
