Hi Laurence,
I would be pleased to tell you what I recall about going to that farmhouse. It was in 1997, so not sure what you mean when you refer to the "new" house there.
I was searching for a location that my great great grandfather James Brew had purchased in 1846. His death record indicated he was from the "Rhaa". Turned out to be a piece of the Rhaa farm sold many years prior.
Write me at laxey@shaw.ca and I will detail what all I discovered about the farm.
