Try wyonewspapers.org - it is Wyoming Historical Newspapers up to 1922. I searched for Colin McDougall and got 44 hits. I have found them in the US Federal 1910 census. If you do not have access to ancestry or other means to access the census - let me know I will print it, scan it and email it to you - let me know your email address.
