http://www.britishnewspaperarchive.co.uk/http://newspapers11.bl.uk/blcs/...Are the online/digitised papers, the newspaper site itself only searches back to 2007. The archived ones are paid-for services and I think in one or both instances cover editions between 1800-1900 so wouldn't have what you're after.
Bangor University Library 'Stack' also has physical copies to examine.
