April 3, 2009 - We have begun to put naturalization indexes onto the Historical Records Database. Just completed is the Larimer County index that spans 1885-1958. We plan on adding additional indexes in the near future for other counties. As of this date we have 773,933 entries in the database.

February, 2009 - We have processed almost 200,000 entries from the Arapahoe County/Denver Lot and Block Index into the Historical Records Database. The index documents property ownership from 1862-1917 in the Denver area. The index, itself, can help researchers find information about particular property and the owners in the time period. It also refers to the deed books where the actual deed is recorded. It is an invaluable index for house/neighborhood historians.
