There are some historical newspapers online.
Irish Newspaper Archives is a subscription website. It has "Wicklow Newsletter" 1900-1926 and other county and regional titles, and national papers. https://www.irishnewsarchive.com
Select "Newspapers" tab to see a list of newspapers and years held. Click on a newspaper title for more information about it, e.g. where published, political leanings &c.
British Newspaper Archive includes many Irish newspapers. In addition, Irish news was reported in some newspapers published in Britain. https://britishnewspaperarchive.co.uk
British Newspaper Archive is also on Find My Past family history website (subscription). You can search under surname. I usually omit forename since many reports didn't include forenames. There are a great many results for "Dublin Evening Telegraph" 1924/5 because a novel with characters named Gilchrist was serialised in it.
There were some Gilchrist sales advertised in "Wicklow People". Thomas Gilchrist, small farm at Hacketstown, County Carlow (1915) and some in Wicklow in 1920s. The reason given for the sale of the property at Tourant was emigration. ( "Wicklow People" 25th April 1925 )
"Wicklow People" had a death notice for Elisabeth Gilchrist, daughter of "the late Henry Gilchrist", followed by an instruction "American papers please copy".
If you extend search years you'll find other, minor matters, some of which came to court e.g. a fine for being without a car licence; poaching; a dispute between a Gilchrist uncle and nephew about ownership of some cattle. Irish Petty Sessions records are online and indexed by surname. Petty Sessions courts were for minor offences.
Was Private Edward Gilchrist, reported killed in action in France in WW1, a relative?
There was an intriguing mention, in a newspaper article published in 1938, of a Richard Gilchrist who had refused to take part in setting fire to a priest's house. I assume it was an historical account, as yeomen were involved. Perhaps 1798 Rising in Wicklow. (I can only read an extract.)
Btw Ubank surname was mentioned frequently in Wicklow press in 1860s because Arthur Ubank was Clerk of Rathdrum Union and his name was on the report of every meeting, until his death in 1866.
Link to your previous thread about Ubank, Moody and Gilchrist.
