So, I have been researching some American Magill families, many of whom have trees that point to an origin at Tullycairn (Tullycarn townland, Donaghcloney Civil Parish). So, I am trying to research whether there were any Magills that stayed behind at Tullycairn. I did find a record of a Henry Magill, Esq. of Tullycairn who died in 1844. (The property then went to Robert Dickson, then to David Bennett, then James Bennett. James Bennett retired from farming and auctioned the property in 1926.) I am wondering who owned the property before Henry Magill, Esq, and what was his lineage.
Then, I stumble on records of another Co. Down estate called Gillhall that is associated with Magills. It is in Ballysallagh townland, Dromore Civil parish, which happens to be immediately adjacent to Tullycairn. There is a lot more information available about Gillhall. Apparently Captain John Magill obtained the property from the Magennis family in the 1660's. John Magill also owned Tullycairn. The property eventually transfered to the Meade family when Captain John's great granddaughter married the Earl of Clanwilliam.
https://en.wikipedia.org/wiki/Theodosia_Meade,_Countess_of_ClanwilliamI read that the Earl of Clanwilliam ran into financial problems in the 1780's and started selling some of his properties. Perhaps this is when Tullycairn estate split off from Gillhall.
Does anyone have any information on these properties and Magill families?
I created a couple of pages on Wikitree about these properties.
