Help researching the Roggow family

  • Help in researching the Roggow family from Preuben/Prussia
    My 2nd great grandfather immigrated to the US March 16, 1870 from Germany. We have no information on his family line. I am hoping that someone somewhere might have information on his parents.
    His name William Christian Roggow born: 27 FEB 1854 • Germany DEATH 23 MAR 1923 • Montana, USA

    He married Margaret Anna Flury
    BIRTH 09 APR 1847 • Conters, Küblis, Prättigau/Davos, Graubünden, Switzerland
    DEATH 24 JUN 1921 • White Sulphur Springs, Meagher, Montana, USA

    Any assistance would be greatly appreciated.
