Am seeking any information about Ernest and Rosina Wolff (Rosalie Guestenburg). They had a daughter, Emma (b. 19 May 1870 in Doniphan Co.) who married George Angus Brown on 19 Apr 1893. Emma died in Atchison Co. on 17 Nov 1959. Her husband, George died on 30 Oct 1912. Any assistance in providing information on the Wolff family would be sincerely appreciated.
