Hi,
In the meantime I have found the parents of my second great grandmother Barbara Lawall. She was born 9 March 1836 in Obersülzen to Conrad Lawall and Magdalena Meder. I do have the marriage certificate for Barbara Lawall and Konrad Bachmann, which gives her parents, so I'm quite certain I have found the right one in the baptism records. I am aware of that other Barbara Lawall.
Thank you for replying to my post.
Karen
