Many North American Magill family trees claim a connection to the Magills of Tullycarn, County Down, Ireland, near Dromore. Much less is known about the Magill family members who stayed behind in Tullycarn. There was another Magill Estate in County Down called Gillhall.
Tullycairn Townland Description, Ros Davies: A townland of 267 acres; 6km from Dromore; click here to see its location on a townland map; means ' hillock of the cairn'; highest hill 296 ft; bog; forest; the proprietor Henry Magill Esq.held most of the land himself but let the remainder at £2 an acre in 1836 : corn mill fire 27 Sep 1851
Tullycairn House Description, Ros Davies: 3km E of Donaghcloney village; the residence Magill family in 1777 & of H. Magill Esq. in 1836; it was described as a conspicuous object at the eastern end of the parish, situated on the summit of a hill with some young plantings around it ; the proprietor in 1795 was John Magill; residence of James Bennett in 1910. 
Another Description of Tullycarn: Tullycarn Hill, the highest ground in the parish, rises to a height of 296 feet above the sea-level. ON the summit is Tullycarn House, formerly the residence of a younger branch of the Magill family, and in all probability built of the stones of the ancient carn which gave its name to the locality. A considerable "moss" lies at the bottom of the hill, and immediately beyond, but in the parish of Dromore, are the demesne lands of Gill Hall, the seat of the Earl of Clanwilliam. Like Many of the families descended from officers of Cromwell's army, the Magills appear to have been originally Presbyterians. In the 'Records of the Synod of Ulster', we have come upon an entry which establishes this with regard to the Tullycarn family, and at the same time shows that in the early part of last century the territorial, if not strictly parochial, system was maintained in the Presbyterian communion. 
"The townland of Tullycairn was bequethed by him (Lord Clanwilliam) to John Magill, in the possesion of whose descendants it remained in until recent years."  This transfer of ownership of Tullycarn could have been as early as 1765 when John Meade married Theodosia Magill and lasted until the death of Henry Magill, Esq. in 1844.

- "Gill Hall", also known as Gilford Hall, was also owned by Magills and is much better documented. It is located in Coolsallagh townland, Dromore Parish, immediately adjacent to Tullycarn. Was this once all one estate owned by the same Magill family? My suspicion is that Tullycairn was originally part of the Gillhall estate, and was sold in the 1780's by Clanwilliam to Magills.
