The more recent the event the less likely to be available online when dealing with local papers.
Checked British Newspaper Archive/FindMypast for Cardiganshire newspapers (they include Welsh Gazette, Cambrian News, Aberystwyth Observer, Cardigan and Tivy-side Advertiser, Aberystwyth Times). They go up to 1951 as far as I can see.
Have you checked the catalogue for Cardiganshire Archives which might list their newspaper holdings? Highly unlikely to be online and would require a visit to plough thru' edition by edition, usually on microfilm.
