Genealogy Research

The Duluth Diocese welcomes inquiries for genealogical and historical research in accordance with canon law, civil law and privacy issues. The Diocese does not allow in-person, on-site research to be done in the Diocesan archives. 

Requests should have as much information as possible:
– Name of person(s) and dates you wish to have researched
– Parish and town where parish is located that they would have attended
– What record(s) you are looking for

The Diocese of Duluth Archives asks for a donation to cover the cost of time on research and queries.  The typical donation is between $15 and $25.
