I had a look at the lower section of Rathgar Rd this morning, both sides of the road from the Servants' Church down to the Rathmines end, but did not see much in the way of old terrace or house names. Although the separate terrace structures can be detected (as per the table mentioned earlier), I could not see any visible terrace name engravings of the type I have seen on other buildings in Dublin City. A number of the houses, particularly on the west side, seem to have been re-faced, and others have relatively rough-cut corner-stones where the terrace name would, I believe, sometimes be carved.
The only familiar name from our previous discussions was an old house-name engraving on Malakoff Villa, which was located on the east side, near to the location of the terrace on the 1848 map. It seemed to be un-numbered but around 184/185.
I was able to confirm the numbering system - number 2 being on the west side almost opposite the junction with Rathmines Rd upr, and across the road (next to the Garda Station) is number 196.
