I have done research on Rose Kuehne (Kuchne)who had a brother Fredrick b. 1884 in Switzerland. I have him in the 1900 & 1920 NY census. Parents are Dominick b.1854 & Rose b.1860. In 1920 he is living with his sister Rose Browning and is listed as Fredrick Kushno. His occupation is fireman and he is single in 1920.
