My grandmother, Marie Elfriede Jung was born in Breslau in 1882. Her father was Frederick Hermann Jung born in 1851 in Silesia and her mother was his English wife Sarah Middleton Jung (nee Riley). Frederick and Sarah had more children in the Breslau area before returning to England with the younger children and were on the England 1911 census. I have been unable to find out any more about his parents or the child/children left in Silesia. Any help on this would be gratefully received!
