I am helping a friend look for his family and saw your posting. He is a Mueller with connections to Indianapolis. Other names in his family are Myer, Hohl, and Roesener. The Roesener is some how connected to an Orphanage in Indianapolis. The name is George Roesener. The Mueller name is changed to Miller by an Otto C. Mueller during WWI. He was a salesman of lumber and veneer. I have a short linage of his Mueller going back to a John A.D. Mueller 1835-1919 married o Caroline Hohl 1834-1924. Does any of this fit into your families ?
