The two buildings on [VO] Griffiths Valuation maps, Dublin county, Township maps, Pembroke, map 22.
The plot numbering ("182" and "113" crossed out) and the acreage here perfectly matches the plot numbering and acreage in [Griffiths Valuation, 1849] for the Michael Dillon house (Gandon building, to the N) and the Algernon Preston house (Newgrove Ave building, to the S).
The Gandon building is marked here as "Sandymount Park House" (which presumably led to its later name of "Park House").
See larger and full size.
Griffiths Valuation period map from askaboutireland.ie.
The Gandon building is now called "Park House".
The other building is still "Sandymount Park".
1887 to 1913 map shows the two buildings.
"Roslyn Park" to the N (the Gandon building) and "Sandymount Park" to the S (the Newgrove Ave building).
