"This street name can be traced back to Hugh the Yellow O'Neill (his estates were referred to in Irish as Clann Aodhe Buidhe as recorded in a map of 1591 as Claneboy which in time became Clandeboye" (Haines and Cooke, East Belfast Paintings and Stories from Harbour to Hills).
Clandeboye is the anglicised form of Ir. Clann Aodha Buí, the name of a population group, a subdivision of the O'Neills in the late Middle Ages, and also the territory which they occupied and controlled. While the seat of the overall chieftain of the O'Neill clan was in Tyrone, the Clandeboye O'Neills were a somewhat less powerful sept descended from one Aodh Buí O'Neill ("yellow-haired Hugh", died in 1283). They established themselves in parts of Cos Antrim and Down during the Gaelic re-expansion which occurred after the murder of the Earl of Ulster in 1333. Here they were forced to contend for land with the Anglo-Norman colony centred on Carrickfergus. Their seat was at Castlereagh. The castle was in the townland of Castlereagh, high up on the plateau, but the exact site remains elusive.
The last Gaelic ruler of Upper Clandeboye (along the southern shore of Belfast Lough) was Con O'Neill (c. 1574-1619), who had much of his land confiscated during the Plantation. At Christmas time 1602 Con was imprisoned in Carrickfergus Castle by Sir Arthur Chichester for sending his men to attack English soldiers. Approximately one third of his land was granted by King James I to the Scottish adventurer James Hamilton, who was later given the title Viscount Claneboye and had his seat at Bangor, and later at Killyleagh Castle. In more recent times the name Clandeboye was applied to a stately home with its estate near Bangor, residence of Lord Dufferin.
