Hello Carol,
Silversprings is still inhabited and in perfect order. It used to be known as the Downs House. The coordinates from Google Earth are as follows: 53° 07' 48.07''W 6° 07' 03.48''W.
The name of the family living there is Cohler.
It has previously been owned by Stoney family and the Slingsby family. I would be keen on any information you have regarding the place as I am trying to compile the history of the Downs village and environs. I do not know the correct postal address but Silversprings, Downs Village, Willow Grove, Delgany, Co. Wicklow should work.
regards, DDHS
