Rudolf Kahler son of Joseph & Selma from Evansville, Ind.

Does anyone know Joseph & Selma Stoltz Kahler who lived in Evansville, Vanderburgh Co.,Indiana? They had a son named Rudolf. Rudolf had a son named George Rudolf Steinhauer Davis with Kate Steinhauer, out of wedlock. I am looking for pictures of this family, as our family have never seen any of them, not even our Grandfather, George. Please look for any pictures you might have and email them to me, if you can. I would be forever grateful. Thank you so much, linda
