The Pottinger family had a large estate in east Belfast but most of it was sold before 1800,
though there is still a district by the name of Mountpottinger.
Maj.Gen. John Pottinger died in April 1877 at his home 'Mount Pottinger', Carrick on Shannon.
Can anyone tell me: was that a house in the town, or did he have something more like a mansion nearby? He is thought to have owned land in Keonbrook townland, but that doesn't necessarily mean he lived there.
Unfortunately he was with the army in India when Griffith's valuation was carried out, and didn't retire until 1863. I don't know what other sources might help in the search. There could well have been a newspaper announcement of his death, or that of his wife in March 1876, but I feel they are unlikely to have given a precise location of the house.
