I am looking for descendents of a Heinrich and Isaak Fast who lived in Corn, Oklahoma, probably in the late 1800's or early 1900's.I have no other information, except that they were related to my gr. grandmother, Susanna Fast, born in 1866.They could have been her brothers?? ..or cousins. Susanna married Herman Kornelius Klassen, and Susanna's sister Anna married Kornelius Klassen, a brother to Herman. Susanna & Anna's father's name was Isaak, probably born around 1827-1834. (Heinrich and Isaak Fast were second cousins to a Katharina (Klassen) Neufeld 3/4/1864-7/22/1940).
