The Minnesota Historical Society has posted an online index to death certificates for the years 1908-46. The index provides the name of the deceased, certificate number, date of death, and county of death. There are also fields available for date of birth, place of birth, and mother's maiden name, although I was unable to locate any entries that contained that information.

Once an entry is located, you can order a copy of the death certificate by just clicking on "Add to order." A printable copy of the order form will be created which includes the entry (or entries) that you have selected. The customized order form can be sent, with a check for the requested amount ($8 per certificate), to the historical society.
