Gloucester Street Upper is now named Sean MacDermott street, Cathal Brugha street is a new street created after the civil war about where the ruins of St. Thomas Church of Ireland were, it overlaps with part of Findlater place.

I had also checked the "MapGenie 6 Inch Last Edition" which distinguished between Cathal Brugha to the West and Sean MacDermott to the East of Marlborough Street. Unsure which map applied to 1915 and plumped for the 25 inch edition.
How can I determine the dates of the maps listed under "Basement Gallery"?

[athacliath62]

the 25 inch is from about 1890-1910
the 6 inch "Last Edition' I believe is estimated to be 1930s so after the civil war the loss of St. Thomas church and creation of Cathal Brugha Street
the two other 6 inch maps are from the 1st OS survey late 1830s to 1840s
the two map genie standard and Eire maps are current, the Aerial views are dated.

The closest map to the way the streets were in 1916 would be the 25inch, the address mentioned would probably have been almost opposite the church, current location allowing for renaming etc would be on the corner of Marlborough street and Sean MacDermott street  (I think the northern side) and opposite the junction between Marlborough street and the "new" Cathal Brugha Street

added - a part of Gloucester Street / Sean  MacDermott street to the east of Marlborough street was apparently reassigned as an extension of Cathal Brugha street in 1992
