Doe Castle was most likely built c.1420 by the Quinn family, but by the 1440s, it had come into the hands of the
gallowglass MacSweeney family. The castle remained in the hands of a branch of the
Clan Sweeney known as ''Mac Suibhne na d'Tuath'' (Mac Sweeney Doe) for almost two hundred years until it was seized by King
James VI and I because the MacSweeneys had rebelled against him. On 7 March 1613 during the
Plantation of Ulster, the king granted the castle, along with other lands, to the
Attorney-General for Ireland, Sir
John Davies (poet, born 1569). On 31 December 1614, Sir John sold the castle to an English settler, Captain John Sandford from
Shropshire, England. It was there that
Owen Roe O'Neill returned in 1642 to lead the
Ulster Army of the
Irish Confederate forces during the
Wars of the Three Kingdoms. The castle changed hands repeatedly during the 17th-century struggle for control of Ireland between the English and the Irish. It is known that in 1650,
Sir Charles Coote, the Governor of
Londonderry, took possession of the castle. Eventually, the castle was bought by
Sir George Vaughan Hart and inhabited by his family until 1843. == Today ==
