Dear Administrators of this Profile:
I have encountered a question regarding whether Rabbi Samuel Zalman Shapira can be the father of Asher Katz. The reason for the doubt is that Asher Katz and his lineage are a Cohanic line, while the line from R' Samuel's other son, Rabbi Shlomo Salman Spira, ABD Heilbron, does not appear to be a Cohanic line. This is further highlighted by the yDNA haplogroups currently assigned to each lineage (for the Asher Katz line it is a J group while for the Shlomo ben Samuel Zalman line it is a G group. So the question I present is whether it would be possible to provide any supporting evidence for the paternity of Asher Katz Shapiro as being R' Samuel Zalmen Shapiro's biological son?
Your Attention at Your Convenience is Appreciated,
Adam
