The monument that once identified his grave was already crumbling by the mid-eighteenth century, and when the old medieval church was finally taken down in 1765, it was destroyed entirely. A new church rose in its place in 1769, but as a correspondent to the Irish Builder noted in 1898, there is now neither monument nor inscription to the family.

The man in question was Sir William Brabazon, who served as Treasurer-at-War in Ireland for over thirty years and acted as Lord Justice, the crown's chief administrative officer in the kingdom, on at least four occasions. The original Latin inscription on his monument credited him with being the first to take Athlone Castle, and with bringing the province of Connacht under Tudor civil order. A secondary English inscription beneath it described him as the first Englishman to plant in Connacht, and noted that he had served under both Henry VIII and Edward VI. He married Elizabeth Clifford, of the Cumberland earls' line, and their son Sir Edward Brabazon, Lord Baron of Ardee, had apparently intended to be buried beside his parents. The monument itself was erected by Edward in his father's memory, though it contained errors: the date of death it gives, 1548, appears to be wrong, with July 1552 considered more likely. Brabazon died in Ulster, and in a further complication of the record, his heart was separately interred with his ancestors at Eastwell in England, while his body was brought to Dublin.

St. Catherine's Church on Thomas Street is the Georgian structure completed in 1769, and it sits on ground that has held a parish church since at least the early thirteenth century. The church is not always open to the public, so it is worth checking in advance before making a visit specifically to see the interior. There is, of course, nothing to see of Brabazon himself. What makes the place worth pausing over is precisely that absence: a detailed Latin monument, an English gloss beneath it, a family's intention to gather there across generations, and now no physical trace of any of it remaining above ground.
