There are actually quite a lot of online sources for this resource although not many of them are free I'm afraid. Some of the standalone services like the Irish Times, Irish Newspaper Archives and the British Newspaper Archive can work out to be quite pricey actually so hunt out deals or perhaps buy a short-term subscription?
Of the main genealogical subscription players, Find My Past is the only one that offers comprehensive access to both British and Irish newspapers as part of its partnership with the British Library to create the British Newspaper Archive. You will need to purchase the right level of subscription to access them, but quite frankly, I think it's worth the money in this instance.
I guarantee that once you discover and start plundering Irish newspapers for your family history research you will be hooked and will welcome any rainy afternoon that keeps you indoors "dead-diving" in the newsprint! How else will you ever find deliciously shocking stories like the one hinted at in the snippet above! And as for your penchant for purple crepe-de-chine, why it was practically written in your genes considering the report of what your great grandmother wore to her son's wedding!
Enjoy!
