William Zane Cozens was born in Canada in 1830. He came to Colorado when he was twenty nine years old and was soon elected sheriff of Central City.

However, in 1874, he moved his family to Grand County where they ranched, established a post office and ran the stagestop in the Fraser Valley.

The house is now the Cozens Ranch and Stage Stop Museum and all that remains of the large ranch complex which once covered over 700 acres.
