On Ancestry, I saw trees which are saying that "Rabbi" Meyer Wallich's father is Maier ben Yitzchak Walch, which obviously doesn't make much sense.
However, I did find in a sefer, and I will post the pictures in media, that Meyer Wallich's father is Rav Yosef Shtadthaugen Joseph de Bonne dit Stadthagen whom we know as Joseph de Bonne, Stadthagen.
Now, I did notice some discussion about Mate Stadthaugen there, whom I don't know yet.
This sefer also has a further discrepency regarding Shimshon (de Bonne) of Mitz's wife, but I will discuss there.
If anyone can shed light on this, I'd greatly appreciate it.
Thank you so much
