I am wondering if you know of any connection between the Oregon, Washington State and Idaho Kupers? The Washington Kupers originate in the US from (Huntz) H. Kupers, born May 12, 1835 in Germany (possibly in the Schleswig-Holstine area). He and his family immigrated to the United States in 1883. They lived in Chicago, IL then moved west to Washington State in 1885 finally homesteading several wheat farms in the Harrington/ Mohler area of eastern Washington. Is there possibility that the Oregon/Idaho/Washington Kupers represent siblings who came to the US and just chose different locations in the US to homestead?
I would appreciate any additional information you may be able to provide!
