Arthur Bollermann came over from Germany and was one of the original owners of the Bollermann & Son Piano Company in New York. He had a number of children with one being my great great grandfather Arthur Martin Bollermann. Arthur Martin Bollermann subsequently dropped the last 'n' on his name and formed his own piano company A.M. Bollerman, Inc. My great grandfather Harold Irving Bollerman (he went by Irving) was the vice president of the company.
