The history of Killagh More, as with many Irish townlands, is deeply connected to patterns of settlement, land tenure, and the social structures that evolved over medieval and early modern periods. The townland system itself, which divides the Irish countryside into these small administrative units, became standardized during the Tudor period and has remained a fundamental feature of Irish geography ever since. The name "Killagh" likely derives from the Irish "Cillach," which relates to ecclesiastical connections, suggesting that like many townlands in Ireland, this area may have had historical associations with early Christian settlement or monastic lands, though specific documented history of Killagh More itself is limited in widely available sources.

Killagh More, like many rural townlands in Connemara, has been shaped by the economic and social realities of Irish rural life, including subsistence farming, emigration patterns, and more recent changes in land use and population distribution. The townland would historically have supported small farming communities relying on cattle, sheep, and potato cultivation, with families often working small plots of land passed down through generations. In common with much of rural Ireland, the area has experienced significant demographic changes over the past century and a half, with emigration and rural depopulation affecting many such communities.

Today, Killagh More remains part of the living landscape of County Galway, contributing to the character of the broader Connemara region. While it may not be widely known outside local contexts, the townland represents the kind of small-scale rural community that forms the backbone of Ireland's cultural and geographical identity. For those with family connections to the area or those studying Irish geography and history, Killagh More serves as a tangible link to Ireland's rural heritage and the complex processes of settlement, adaptation, and change that have defined the Irish countryside.
