I am not sure if this is the same Frank Hoff(b.1857) (AKA Francis Xavier Hoff) that I am trying to find information on.. I do know that he immigrated from Switzerland in 1875 and was married to an Elizabeth ? (b. 1851 Ireland) formally married to a Miller and she had children from her previous marriage a Gertrude, Anne and a Henry Miller and Frank and Elizabeth had 3 sons. Frank, Albert and Arthur. I am trying to find more on the Miller side as well as the Hoff side. I want to say that Arthur is my Great Great Grandfather on my Grandmothers, mothers side. According to the 1930 census listing Arthurmarried to a Mary along with my Great Grandmother and her sister and a Gertrude Gebhartd? listed as Arthurs' sister. they lived in Wichita Ks and he was born in New York.
