I haven't come across a Clounagh House either. I get the name from (hand-written) records left to me by my ancestors. I have noticed a school in Portadown named Clounagh. I wonder if it is on the site where Clounagh House was situated. Or was there a village called Clounagh, or maybe just a Hamlet?
My ancestors who (are noted to have) died in Clounagh House were George Ripley and wife Mary Ann, nee Sturgeon. (George's mother was Sarah Donaghy). The years 1875 and 1897 don't seem that long ago, genealogically speaking, so would expect there to be some kind of record of Clounagh House's existence.
I have found on records (on the web) that Mrs Mary Ripley had a Grocers business selling also as a wholesaler and selling spirits. Against that listing is, Clounagh.
In 1888, there is a residential listing of a Thomas A Ripley, Clounagh. Mrs Mary Ripley had a son, Thomas Andrew Ripley.
Now, I have also looked for other names listed in Clounagh and I came across 2 sets; 1. Charles and Edward Clayton 2. John and John Jnr Ferguson.
That makes me think Clounagh was the name of an area in Portadown and maybe within that area was a house called Clounagh House. It may have just been a cottage with that name.
It's a mystery!
I am not connected to John and Mary Woolsey. But there was a George Woolsey listed on the business directory in the 1880s, address as corner of Thomas and Market Streets, Portadown. He is listed as a Grocer and Baker/Flour Dealer.
On the list of residents in 1888 is listed a B. Woolsey, Kilmoriarty, Mullantine.
