I am descended from the Aron family in Freudental. This was a fairly small family in Freudental. The Aron Family descends from Nathan Mayer Abraham. His son was Aron Maier (Aharon ben Maier) (1734-1822). Aron Maier's children, including my ancestor Mayer Loeb Aron (1779-1861), took the surname Aron.
Aron Maier's wife was Elisie (Elichie) Kahn. There was a Kahn family in Freudental, however, no evidence points to her being related to that family.
Mayer Loeb Aron's wife was Heffele (Hundle) Dreifuss (1788-1839). Her parents were Samuel Dreifuss and Kele ??? I have no information what town they came from.
Most of this information comes from Der juedische Friedhof in Freudental (see Books).
Moses Hayim Aron (1820-1876), son of Mayer Loeb Aron and Heffele Dreifuss moved to the town of Ludwigsburg. His wife was Amalie Kuppenheimer (1832-1883) from Kuppenheim. The book Juedisches Leben in Ludwigsburg (Jewish Life in Ludwigsburg) by Joachim Hahn discusses their family.

Der juedische Friedhof in Freudental by Bez, Goren, Antman, and Graef. Published in 1996 by W. Kohlhammer. 303 pages. The overwhelming majority of this book consists of pictures of the headstones from the Freudental cemetary. The entries also cross reference the town records. Nearly every entry includes a picture of the headstone. It is an excellent reference for someone researching the Jewish communiy.
If you have any information about the Jewish community in this town or have ancestors with the same surname, please contact me.
