The legacy of St. David's occupants testifies to their prominence and affluence. The coffins unearthed in a previously unexplored vault in 1990 were of a quality rarely extolled, much less seen during this period. They were velvet covered, lined with cloth, and padded with hay, adorned with decorative roundels of metal and embellished with a coat of arms and a crest. Although the existence of a vault belonging to the Lattin family has been recently validated, their eminence was such that they would not have been interred within the chapel after the Reformation. The vault probably belongs to the Mayo family of Palmerstown, the De Burghs of Oldtown, or the De Robeck's of Gowran's Grange.
Memorials also exist within the church commemorating inveterate occupants who frequented the church.
One window on the north side of the church serves as a memorial to the late Earl of Mayo, while the east window is a memorial to the late Rev. Walter de Burgh, for twenty nine years vicar of the parish. Other prominent Protestant families of the era, although not so lavishly acknowledged, would have been Sotheby, Eustace, Bourke, Jones, Forster, and Nevill. Aspects of St. David's The present Church of St. David's is but a portion, though undoubtedly the larger portion, of the original edifice. Of the three chantries which once existed there is no palpable manifestation. The chantry of St. Catherine may have stood in the present nave, the chantry of St. Mary in the present aisle, and where the chancel currently stands, would have stood the chapel of the Holy Trinity.
