So far as I know, all members of this line were born in this town, now apparently incorportated into Karlsruhe. All were baptised in St. Martin RC church there. My grandmother was Karolina Eberle, b 2/14/1875. Her parents were Jakob Eberle (1837) & Thekla Volk (1836), m 8/16/1864. Jakob's parents were Wendelin Eberle (1783) & Sabina Dehm m. 1818. Thekla's parents were Lorenz Volk & Franziska Merk. I pass this on because of similarity of first names, but the towns don't jibe. I have wondered why my grandmother and a sister came to USA while no previous members had come and your thread seems a plausible connection.
