Is there anyone on the list willing to do directory lookup for Rio Grande from 1910 going back? My great grandfather was in Creston Iowa in 1900 census, in 1910 was in Rio Grande census. Am trying to find out when he moved there and if the directory shows who was with him. His name was Harvey W. Whittlesey, might have also used William H. Whittlesey. Have reason to believe he was only in Rio Grande for a couple of years and before that was in Denver CO. Thank you, Donna
