What is the availability of catholic church records in the Margraviate of Baden in the 19th century? (I know that the diocese of Regensburg is still stalling digitizing theirs, and there may be a religious motive.) All I have access to is duplicates, created by decree and stored with the civilian authorities, covering the period from 1810 to 1870 and now available online at the State Archives in Karlsruhe. (The transcriptions on FamilySearch are quite incomplete and riddled with mistakes.)
I am looking specifically for records in the village of Hörden, a branch parish of Gernsbach, and within these records I am trying to research a man named Joseph Rahner. There seem to be three people by that name, Rahner-24 (abt 1780-1859) and his father Rahner-25 (abt 1752-1827), as well as a third Joseph Rahner who is identified in two records as "Michel's son". The village of Hörden is quite small and dominated by four last names (Rahner is one of them), so I am convinced that there is a family connection, and I rather suspect that Michael Rahner is a brother of Rahner-25.
Is there any way to prove this?
