As a result of changes to landownership and the settlements of the seventeenth century, the character of the Sixmilewater valley was transformed. At the beginning of the 1600s, Sir Arthur Chichester acquired a huge estate in south Country Antrim. This included lands in the Doagh area.
Chichester is credited as the man responsible for laying out a large deer park in neighbourhood of Doagh – Parkgate takes its name from the fact that it was one of the entrances to this park. Another entrance lay between Doagh and Ballyclare and was known as the Thorndyke.
What exactly was happening in Doagh in the early seventeenth century is something that we cannot be certain of. It seems probable that Scottish settlers arriving on the east Antrim coast were pushing inland along the Sixmilewater valley and many were acquiring farms in the Doagh area and setting up home here. It is not until the 1650s and 1660s that we can gauge the impact of Scottish settlement in this district.
The hearth money roll of 1669 shows that Scots were overall very much in the majority in the Sixmilewater valley. In Doagh at that time the surnames included: Adam, Allen, Bell, Browne, Hamilton, McNeely, Porter, Rea, Rowan and Wallace.4 As a result of the immigration of these families, the area became strongly Scottish in character. The impact of the Williamite War was felt in the area in the winter of 1689-90 when Danish troops were billeted on the inhabitants of Doagh, Donegore, Kilbride and Rashee.
