Consider these things when searching for a name:
A. Search (Google or Zoom)
1. Due to some pages that are long, many of the names are not picked up by Google, generally those farther down the page. [By design Google only indexes a certain distance down the page.] This website provides a search, called ZOOM, that completely indexes all names. For best success, use it. To use the search for Colorado Cemetery Index go to the link at the top of the page labeled Co Cem Index Home. To do a complete search of the Online Archives, currently 8 sub-sites, go to CGHS Online Archives.
B. Other considerations
1. Spelling. The compilers of the source publications could spell. However, they used such things as cemetery records or logs where the keeper of the records often did not know the spelling of the names of the interred persons. One such record, that of the Idaho Springs cemetery, is notoriously bad. Also, reading tombstones that are deteriorated sometimes have different transcriptions.
2. Different spellings of names that start with Mc or Van, etc. Some had a space after the Mc or Van, some don't. Look for both versions. The ones with the space sort before those without.   Examples: Mc Donald - McDonald or Mc Ginnis - McGinnis.
3. Unknowns. Check unknowns, there are a number with good detail, but the last name is not known. Check under "U".
4. When two sources are found for the same cemetery or burial site, the names, on occasion, are recorded with different spellings. When this was found to be the case, both spellings were shown in this index, but the entries were not duplicated (one line for each of the spellings). Rather, they were listed like this: Smith/Smythe, Donald/Donal, or Dennis/Denning.
5. There are some entries showing a person buried in more than one location (cemetery). In most cases, expect this to be correct. There were several reservoirs constructed in Colorado where cemeteries were flooded and bodies had to be removed to other locations. Also, other construction projects, such as interstate highways, where the same thing happened. However, there are also some instances where families removed bodies to larger or more modern cemeteries for personal reasons. Thus they might be listed both places.
