The designation itself, a settlement cluster, refers to a grouping of related habitation features, typically the collapsed remains of stone walls, house platforms, field boundaries, or enclosures that together suggest a community once lived and worked in close proximity. Mayo has no shortage of such places, many of them abandoned during or after the nineteenth century, others reaching back considerably further into the medieval or even prehistoric past.

Beyond its classification and location, the specific history of this particular cluster remains undocumented in any accessible source at the time of writing. Whether it represents a post-medieval farming hamlet, an earlier nucleated settlement, or something older still is not yet known from published records. Mayo's landscape carries the traces of successive waves of habitation, from early Christian farmsteads to the dense pre-Famine townland populations that were scattered by emigration and clearance, and a site labelled only as a settlement cluster could belong to almost any of those chapters. Until a more detailed record becomes available, Bloomfield holds its past without much elaboration.
