HOLYHILL HOUSE, near Strabane, County Tyrone, is a plain, three-storey, five-bay Georgian house.
The demesne and house, located in the townland of Hollyhill and the parish of Leckpatrick, date from the late 17th century.
Holyhill House, whitewashed, three-storey with five bays, seems be ca 1736, when William Starratt surveyed of the estate.
It was originally attached in front of an earlier house, which was removed in the early 19th century and replaced with the present building.
Sir Allan sold the property in 1983 to Hamilton Thompson, a Strabane pharmacist.
“Ballyburny alias Holihill” belonged to “James Hamilton Esq. a Minor Sonne to Sir George Hamilton ye Elder” before 1641 and was distributed to Sir George Hamilton afterwards.
This first house was burned in 1641, and at some time thereafter the property was granted to the family’s agent in the Strabane barony, David Maghee, whose son, Captain George Magee, sold the house to the Rev John Sinclair, who came to Ulster from Caithness and was instituted in the parish of Leckpatrick (in which Holyhill is located), in 1665-66, and to Camus, 1668”.The residence purchased was rebuilt after 1641, either by James Hamilton or one of his immediate descendants.
“When you chance to see Mr Sinclair of Hollyhill, tell him I have not the counterpart of his deed of Holyhill; and that I therefore desire he will give me a copy of it. If he seems to think his title called in question, you may say you know of no such thing, but that you believe I am desirous of having my privileges ascertained.”On his retirement in 1757, Nisbitt recommended to Abercorn that Sinclair take his place as he was “a rough honest man.”
He was succeeded at Holyhill by son George, who had been apprenticed to a linen merchant.
