And Claudius Bernhard, widower, married Maria Barbara Grissinger(?) 29 Sep 1711 at Urach. This could be Maria Rosina's parents but the mother is Maria Dorothea on all the children's baptisms from 1718 to 1735. There are a couple of baptisms in 1712 and 1717 where the mother is Maria Barbara. Then a Maria Barbara, widow of Claudius, is buried in 1748 but her age is 77 so she would be too old to be Maria Rosina's mother.
So, I think I'm still looking for Claudius's marriage to Maria Dorothea. Edit -found it, in 1716. Claudius (or Claudig?)'s name has been mistranscribed on that one. Not made out what Maria Dorothea's maiden name was yet:
