The disappearance is almost total, and were it not for a handful of documentary references and an aerial photograph, the house might have slipped from the record entirely.

The Civil Survey of 1654 to 1656, a detailed Cromwellian-era accounting of Irish land and property, records the building as a "house coverred with thatch being the sd Piers Butlers Mansion house". Piers Butler, described as "of Mynerstowne gent Irish Papist", is listed as proprietor in 1640. The designation "Irish Papist" was the survey's standard bureaucratic label for Catholic landowners at a moment when such ownership was under severe political and legal pressure following the Cromwellian conquest. A thatched mansion of this period would not have been a modest structure; thatch was the prevalent roofing material across all social levels in Ireland at the time, and a building described as a mansion house in the Civil Survey would have been the principal residence of a landowning family. The house may correspond to a building shown in the centre of Minorstown on the first edition Ordnance Survey six-inch map of 1843, and it is still visible on the revised edition covering 1901 to 1905. By 1977, however, an aerial photograph shows it is gone. Two large barns, a shed, and a new roadway south to a modern house now occupy the site.
