Double name reversal was very common. My late father Max Knisbacher was Markus Mendel on his Palestinian Citizenship Order (British Mandate)
of 11 January 1937 and entered the U.S. in October 1938 under that name. It was based on the Hebrew Mordecai Menahem. In the U.S. he reversed those names and the reversal was how we knew him growing up and is recorded on his tombstone. He always went by "Max" growing up in Berlin (born 1913) and made that official on his U.S. naturalization.  Jeff Knisbacher
