Edward Schultze was born about 1844. He married Ida Kate Ross in 1875. In 1880 he was listed as a tenor, singer. Maybe also in the theatrical field as it seems many associated with the family was. I don't see him after 1900 census. He passed away before 1915, mentioned as deceased in Leonard's passport application in 1915.
Listed as Ernst Friedrich Edward Schultze in Ida's DAR records. On his son, Leonard's passport application he is listed as Edward Fred. Schultze.
