Boulder Mortuary Records
BGS has recently digitized the mortuary collection gathered and alphabetized by member Mary McRoberts from a number of different local mortuaries. These records span nearly 100 years, and many are annotated with additional information. Each record is marked with the name of the mortuary except for the Howe records. Because they are the most prevalent, any record without the name of the mortuary at the top can be assumed to be from Howe. A big thank you to Morrell Printing Solutions in Lafayette, Colorado for scanning this project for us.
