There was a Mordechai of Pinczow who was the father of @Israel Joachim Pinczower and the son of Shalom.
There was a Mordechai of Pinczow who had a brother @Avraham Aba Shapiro and was the son of Pinchas Shapiro.
Is there a source for these Mordechais being the same person and the father being Shalom Pinchas?
Maybe there were two. One the son of Shalom and one the son of Pinchas.
