Although I am not related to this surname of Kuxhaus, I do have access to the obituary of Johann Fredrick (Fred) Kuxhaus, who was born in Rosenburb,Russia, in 1901 and died in 1981 in Sheridan county, Nebraska. He was the son of George Adam Kuxhaus and Mary Kuhlman Kuxhaus. If you are interested, contact me at:
