It is the kind of place that appears on heritage inventories without much accompanying detail, which in itself can be a kind of signal. Graveyards in rural Connacht frequently occupy ground that was considered significant long before formal parish boundaries were drawn, and many are associated with early medieval ecclesiastical sites, children's burial grounds known as cillíní, or the remnants of small local churches whose walls have long since dissolved into the surrounding fields.

Without more detailed documentation currently available, the specific history of this particular burial ground remains elusive. Killeely More is a small rural townland, and graveyards in such settings often preserve the names and dates of several generations of local families, sometimes stretching back centuries, with the earliest markers worn smooth or lost entirely to weather and time. Some such sites in Galway are associated with pre-Norman foundations, where a saint or local holy figure gave their name to the place and drew a community of burial around them across the generations. Whether that is the case here is not yet clear from surviving records.
