For Genealogists

family tree

There is quite a bit of Information for genealogists on this site - it is best accessed using the search feature above.  Note that I have almost zero additional information - it is all on the web site.  If you contact me, I will be polite but I don’t have any additional information. The best additional source of info for researchers is at the Cobourg Library where they have a local history room stocked with many historical books and documents. They do have some photos on-line but not much more - you need to visit.

Covid-19 - currently closed to the public Details here.

Northumberland County looks after the historical archives for Cobourg.  They are currently located at the Cobourg Public Library at 200 Ontario Street (corner of Albert Street and Ontario Street).

They have a good collection of material and have two staff:

  • Abigail Miller – Records and Archival Services Coordinator
  • Katie Kennedy – Records and Archival Services Assistant

They offer:

  • Research support
  • Access to artefacts and documents representing lives from all over Northumberland County - historical and contemporary - including municipal records, family and genealogical records, property records, photos, maps, and other items
  • Programming-in-class 'Intro to Primary Sources' for young primaries, as well as a comprehensive lesson package for Grade 3 entitled 'Life in the 1800's in Northumberland County'
  • Engaging tours to small groups, which can be customized by interest.

You can research Cobourg History but genealogical research is best done at the Cobourg Library (same building – more on the Library here).

The archives will work with educators and offers personalized educational programs targeted towards the specific needs of students.

A new building is planned (currently under construction) when the services will be expanded to include:

  • Enhanced community programming for all age levels, including specialized programming for the residents of the Golden Plough Lodge
  • A permanent display about the history of Northumberland County
  • Changing exhibits about content important to Northumberland residents, developed in collaboration with community groups
  • An expanded reading room for public research
  • A forum for community groups to showcase the stories they wish to tell.

Details on the planned upgrade are provided here.
