The name Eyreville points to a house or estate associated with that family, though the details of the structure itself and its precise history are not well documented in surviving accounts.

The Eyres were a Galway landed family whose influence in the region extended across several generations, and their name survives in a scattering of local placenames in this part of the county. Newtowneyre as a toponym suggests a settlement or planned village associated with the family, a common pattern in post-medieval Ireland where improving landlords laid out new towns or reorganised existing ones and attached their own surnames to them. Whether Eyreville itself was a principal residence, a lesser house, or simply a named holding within the estate is not clear from what remains.
