I have found the following website that does have some census for each county. You have to click on each counties' name to find out what is available. I looked at the Teller County census for 1900 but I didn't see Carrie or John. http://ftp.rootsweb.com/pub/usgenweb/co/http://ftp.rootsweb.com/pub/usgenweb/co/
I hope you find them. I will keep a lookout since I am also looking for family in Teller County - Cripple Creek and Altman, Colorado.
