Andrew Kleim
Andrew cash-claimed a quarter in 6, 6N 48W in 1891.
Might be the Andrew Climie, born June 1857 in Ohio, married Clara B. Vandermark in 1887, recorded in Denver, and in 1900 is a car inspector in Lake County, with son Mark A. Oct 1893 Colorado. Clara was born October 1868 in Colorado.
They're in Denver in 1910, still a car inspector, and in 1920, living with Mark, who now is married.
Clara is widowed in 1930 Denver,

Another possibility is that the Logan County Andrew Kleim is actually related to the KEIM families, just a couple miles north.
