I have some information on Harry Cogeen. He was born in Laxey around November of 1862. He appears on the federal census of 1900 in a mining camp at Carson City, Colorado, married to my great-great grandmother Irma. He has three daughters: Nellie (Cornelia, my great grandmother), Lila, and Marion. I lose track of him after 1900, but his wife, Irma appears in the 1910 census in the mining camp of Lewistown, Montana as a widow. I believe there might also be some connection to Michigan. Some records call him Henry, but, I'm sure his true name was Harry.
