Yes, we were in Grünmettstetten 3 weeks ago. We spent 2 weeks in the area. There are 2 major Steimle lines. The Katholisch from the Horb and Empfingen area as this area remained Katholisch after the reformation. The other Steimle line centers in Calw, Liebelsberg and Neubulach area north/west of Stuttgart which has been Evangelisch since the reformation. We also spent an afternoon with the family genealogist of the Evanngelisch line. Our Steimle line was more specifically from the village of Wiesenstetten. I can provide you more information on them if you contact me on my gmail address at edcarolemc.
