Orangegrove
Templeton, Robt., M.D.
Maryvale

Myrtle Field etc
The house must have had notes in the Ulster Arctitectural historical Society. They may have done a South belfast pamphlet. The house should be dated in a geography [Queens Uni ]MA as south Belfast was completed by Trevor Carlton

Orangegrove Magheradrool . house & farm; 2km SE of Spa; residence of John Macubrie in 1837 & Robert Macubrie in 1863; photo available old b/w map M11; IIW V4 p101 I didnt get studying the Griffiths maps that accompany the askireland version of Griffiths survey but it must have been on the little plateau where the old stranmillis road meets malone Road on the LHS going out of belfast. I think plot 8 might be it on the older amp 1858? corner . Googling and you can see a very large modern building on the old site. I didnt get chasing Drumbeg in Griffiths or O 'Neil in Ros davies, sorry must close now, Jim
