Hello Guy,
I thought i would contact you and let you know that there are three articles that appear in the 'Western Mail' relating to the story of Edward Davies who murdered his wife in 1893.If you were looking to get hold of images of the newspapers, this can be done by contacting Cardiff Central Library. The storey appears in the paper on the 15th, 17th and 21st of July 1893.
Best Wishes,
TallPaul.
