In 2002-2003, the construction of a new road to bypass the village of Toomebridge, Co Antrim, through which the main Belfast to Derry Road (A6) passed, was commenced by Roads Service; an Agency within the Department of Regional Development. As part of the overall planning permission for the Toomebridge Bypass, the Northern Ireland Environment Agency (NIEA) raised a requirement for archaeological mitigation. Northern Archaeological Consultancy Ltd was appointed to undertake the archaeological excavation of this site. In the course of topsoil stripping a small drumlin on part of the road scheme 2,100 flint artefacts were uncovered. While the majority (approximately 70%) of these dated from the Late Mesolithic, the Earlier Mesolithic, Neolithic and Bronze Age periods were also represented. Archaeology was uncovered on the western side of the drumlin. It formed 14 discrete areas (Features 1-14). The features were for the most part structures and ranged in date from the Mid-Mesolithic (Features 1-4), through the Late Mesolithic (Features 5-8), the Bronze Age (Features 9-11), and the late Bronze Age or Iron Age (Feature 13) and the 19th to 20th centuries (Feature 14).

Ireland's First Settlers tells the story of the archaeology and history of the first continuous phase of Ireland’s human settlement. It combines centuries of search and speculation about human antiquity in Ireland with a review of what is known today about the Irish Mesolithic. This is, in part, provided in the context of the author's 50 years of personal experience searching to make sense of what initially appeared to be little more than a collection of beach rolled and battered flint tools. The story is embedded in how the island of Ireland, its position, distinct landscape and ecology impacted on when and how Ireland was colonised. It also explores how these first settlers evolved their technologies and lifeways to suit the narrow range of abundant resources that were available. The volume concludes with discussions on how the landscape should be searched for the often ephemeral traces of these early settlers and how sites should be excavated. It asks what we really know about the thoughts and life of the people themselves and what happened to them as farming began to be introduced.
