I have a Friedrich Dietrich Grabow B. @1840 m. Carolin Grothe: Children: Friedrich William Grabow B. 1866 and Gustave Grabow B. 1877. I hope that these are the right parents. Friedrich m. Bertha Bon in Milbank. Gustav m. Louisa Martha Liebe in SD. Gustav and hiswife had 9 children and one was Harvey Herman who married Mabel May Kasuske. This is my husbands aunt. Are we together on any of this. I can't prove the first Friedrich yet.
