From Rabbi Scott Kalmikov, about his 6x great grandparents

"Rabbi Raphael Ries and Rebbetzin Miriam Levy Ries.
Rabbi Raphael served as the rabbi of Endingen and Lengnau from 1788 until his death on May 25, 1813. Rabbi Raphael’s son, Abraham Ries, served as rabbi of the two communities following his father’s death.
From 1776 until 1866, Endingen and Lengnau were the only places Jews were permitted to live in Switzerland. Jews were not allowed to own property and Jews and Christians were not allowed to live under the same roof. Many buildings in Endingen and Lengnau were built with two entrances, one for Jews and one for Christians. Many of these two-doored buildings still stand in both villages. In the 19th century, half of the population of Endingen and one-third of the population of Lengnau was Jewish. Starting in 1866, Jews were permitted to settle anywhere in the country. Many left Endingen and Lengnau and moved to the large cities. Today, there is only one Jewish family, the Bloch family, still residing in Endingen."
