One the wives of R' Aharon Yehoshua Eliyahu Hertzfeld, ABD Königsberg and Rawitch, is currently marked as a daughter of Rabbi Shaul of Amsterdam (in Hebrew). In fact Ahron Yehoshua had son R' Saul Rawitcher Hertzveld, A.B.D. Tomaszow and then Warsaw (currently connected to a different wife!). Is this information accurate?
