All I have is a newspaper obit on my great grandfather that states Felix died in 1905. Felix's brothers were Robert whose obit had this information and Arnold. It also states that the two sisters names were Agathe Hoffmann and Jenny Hoffmann Adler. Both Agathe and Jenny lived in Ottawa, Kansas and Arnold lived in San Francisco, California. Robert and Johanna "Hannah" lived in Alton, IL and owned a confectionary business. In another article on the father Wilhelm Hoffman it states that Felix lived in St. Louis, MO and that Arnold lived in Albert Lea, Minnesota instead of San Francisco. And in that same article it states that Agathe Hoffmann lived in Warsaw, IL. They must have moved after the death of their father. Felix apparently had a daughter whose name was Louise Hoffmann and she married a ??? Bower. Does any of this sound familiar to you. Well, let me know if you think there may be something. Thanks from the heart.
