Moses Hayim Aron (1820-1876) was born in Freudental. He was the son of Mayer Loeb Aron and Heffele Dreifuss. He 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.

Juedisches Leben in Ludwigsburg (Jewish Life in Ludwigsburg) by Joachim Hahn. I do not own this book. I got it through interlibrary loan and copied the information about Mayer Loeb Aron.
