Harav Menachem Mendel of Przemysl / מנחם מענדל מרגליות-שטענגן מ'פשמישל - Rabbi of Pinczow? (Menachem Mendel Stangen Margolioth)

This source lists R. Menachem Mendel Stangen as the rabbi of Pinczow for about 20 years. It looks like some of the footnotes are for at least one of the books in the profile about section. Have any of the managers or followers of this profile looked at the other sources listed for him in the footnote in this source?
