Hello Dianne, I know that this is no help, but will answer anyway. I have been trying to find more information on my husband's grandparents, Timothy and Catherine Harrington. They did have a daughter, Mary who was known as :Mamie". The difference is that our Harriingtons were in Dogwood, SD in the early 1880's before they moved to Victor, CO. Though other family members of my husband's were in Leadville at that time, not the Harringtons. Wish I could be of help, Jean
