Hi Grant,
I've been researching my ancestral Stewart family around Dalguise for a while now. I believe William (husband of Grace McIntosh) is listed on the Stewart Atholl census in 1817, along with 2 of his brothers. They are recorded as descending from the Cairney branch, which would make them related in some way to the owners of the Dalguise estate. I wonder, would your Uncle have knowledge of his family being related to the historical Lairds of Dalguise? It must go back quite a few generations, but I'm just wondering if a story might have been passed down?
many thanks,
Jason.
