Hi there! I know of an Edward Schermerhorn from Chicago IL. He is a retired police officer with the Chicago police department. I believes he lives in Missouri, or at least he did the last I knew. He told me he had a son who worked in Chicago. He knew my birth mother in 1955. I believe he said his son was deaf. Does any of that sound familiar? If so, I may know more. Please email me and let me know if this is the same person.
