http://www.foothillsgenealogy.org/http://history.denverlibrary.org/research/denver_obit_projec...These are the 2 places I go to check on obits for Jefferson County, Colorado. I did not find the Harvey you speak of. Maybe I can't see anymore, but?
You speak of a death index record? Is it a SSN index?
I do not know of many other sources to check. Other than the cemetery or requesting a death certificate?
