I grew up in Marion Ind. I have a l954 phone book and a Max Mauller is listed in it on 33rd St. Since this is quite old I would suggest you write to the Indiana Room Marion Public Library 6th and Washington St. Marion Ind. 46952 and ask them to look up the people you are seeking. ask if they have obits death dates. they have indexes on this. and are very good to help. they do not charge by the hour. so you would not come up with a large bill.
