Thats what I had suspected Id seen documents online from that time period referencing a Jose Monserrate Marxuach but none referencing a Jose Maria It could be that some archivist or government historian saw Jose M Marxuach on some official document and simply assumed the M stood for Maria Jose Maria being a common enough name combination A photo if any exists in the possession of the family could be compared with the official mayoral portrait for id purposes then again brothers tend to look alike This might be difficult to sort out In any case thanks again for checking   PS If this gets solved you might want to contact someone in an official capacity to let them know of the mistake assuming there is a mistake in which case you would be getting due credit for your thorough investigative work Just a thought
