M.M. Kingman bio from history of North Central Washington 1904
Morrison M. Kingman, president of the Chelan Water Power Company, and a progressive, influential citizen of his community, resides at Chelan, Chelan County. He was born at Spirit Lake, Iowa, June 26, 1859, and was reared principally in Minnesota whence his family had moved owing to the Sioux Indian War of 1862. When eighteen years of age he went to the Black Hills, where he mined until 1883 and then went to Alaska and prospected in the vicinity of Pyramid Harbor. Subsequently he lived in Wyoming, Colorado, and Montana, engaging in lumbering, and afterward came to Spokane, Washington, and thence to Davenport, the same state, where he engaged in contracting and building. Having located some mining claims in Horseshoe Basin, he removed t3o Lake county, Oregon, where he conducted a sawmill in the vicinity of Silver Lake.
It was in 1889 that Mr. Kingman came to Chelan County, since which period he has prospected industriously every season. Associated with A.M. Pershall, he located the first mining claims in the basin. They sold the Blue Devil and Black Warrior claims in 1890, silver and lead propositions. They have since disposed of the Davenport. Our subject owns only one claim there at present, the New Era, in partnership with J.F. Samson. In 1892 he purchased a saw mill which he conducted eighteen months and disposed of the property to his brother, Herbert.
Our subject organized the Chelan Water Power Company in October, 1902, having a franchise in Chelan and Lakeside, furnishing power, light and water. He laid out and platted West Chelan in the spring of 1902, and owns a home in the same addition, which offers a fine view of the lake. Mr. Kingman has one living brother, Herbert. He is a member of the K. of P., and politically a Democrat.
