Hi Tony, just to clarify, the area in the immediate vicinity of the "new barracks" was called Barrackton, it was an area not a street, Avenue or road, in my memory there was not one singular street or square that would have houses numbered over perhaps 50- 60 (but am open to correction as it is a childhood memory) however on the other hand Old Youghal Road or more correctly Youghal old Road started way to the east in the Mayfield district went through an area known as Dillon's Cross and then to the West became the main arterial road in Barrackton passing the entire South wall of the barracks and it's entrances. I have being doing some digging and it would appear that 117 should lie between Harringtons square and Dillons cross to the east of the barracks and on the south side of old youghal road, however on the digitised maps I've seen do not show the number 117, neither does a general search, there may have been some rebuilding in the immediate vicinity or it may be one of the properties that were burned down by the "Auxiliaries" ( Crown forces) on December 19/20 1920 during the burning of Cork, I will visit the area in the next fortnight and see if I can throw any light on the subject!. I am also amazed that your gfathers birth record doesn't give more info on the address, perhaps the street name was shortened or was "ditto as above" . If you could I would look back at this . I will check the 1901 census to see if 117 exists then cheers, J
