In his talk to Voices from the Dust LDS Ottawa event in Saturday afternoon Ken McKinlay, who blogs at Family Tree Knots, mentioned a resource new to me. Belleville History Alive, a partnership between the Belleville Public Library and Community Archives of Belleville, has produced an index to births, marriages and deaths mentioned in the Belleville Intelligencer.
The files are pdfs and some are big. Exercise patience. Entries are in alphabetical order by last name, first name and provide a date of the event and when published.
