The York's lived at the power plant at the mouth of American Fork Canyon in 1930. William was born in 1892 and Ora was born May 14, 1894, in Pleasant Grove, Utah Territory to Hans and Sine Pederson Rasmussen. She married Emmet Nephi Hallsey June 12, 1911, and they had two children: Verlon and Orval H. They divorced soon after and she married William York in 1921. Apparently William had been married before because at the 1930 census they had two children living with them: John York and Orval Hallsey who were both 16. Ora died August 3, 1931, at 37 years of age and is buried in the Pleasant Grove City Cemetery.
