Hello Dan & D.J., For the record, there are Koenig's in Renchen, as I have a one who married one of my Stecher's. I'm out of touch with my research, having been away from my files and work for many months, and a laptop that is in long term rehab, but wanted to at least touch base. Johann Koenig, son of Moriz Koenig (Glassmaker) & Julianna Maier, was born July 11, 1836 and died Nov 3, 1910. Johann married Victoria Stecher in Renchen on May 21, 1863. Johann & Victoria had an illegitimate son Sebastien, born Jan 27, 1862. I do not yet know of any additional children, but have a long way to go. Fully aware that this information may not be of assistance. Familienbuch pages of the Renchen Catholic Church were indeed filmed. I have the microfilm on permanent loan at my local FHC. Kindest personal regards, Linda Rains
