This is my great-grandfather-my grandmother's father...
He is mentioned in the book "The unbroken chain", I don't have the book,but I doubt it has any information about the origin of the Rajzman family.
From a check I made, I found information according to which the family is a branch of one of Shaul Whal's daughters who left Poland and moved to the city of Reiz in the state of Bavaria.
...
I also received additional verification from a group on Facebook that checked that the origin of the family is either from the Bing (Bingen) family or as I found:
Rabbi Simcha Rajzman
Does anyone have any information that can help me? Does Jacobbi have any information on the subject?
TIA
