I have an ancestor, Emily Jane (BUCK) FULLER in McHenry, Marengo, Illinois. She was adopted by an uncle, Gideon L. BUCK; his parents were Ebenezer and Jane (Cusick) BUCK of New York.
The Buck's relocated to Marengo, Illinois where Emily married Walter Asa FULLER in Woodstock, Illinois. They started a family in Marengo before relocating to Minnesota in 1883.
I can provide further details on this history should it be needed.
