Interesting question. I would first ask how many Szapiro families there were in Czyzew and how large the Jewish community was in the 1890s. This guy is a century older than her and I'd want to know how long he was in Czyzew and whether any of his kids stayed there.
By the way, he's my 7th cousin several times removed. Looking at Rosenstein's book and having been to many of these towns in June and July, I realize that in this region each of these rabbinical families was a Katzenellenbogen cousin branch and married each other.
