George, 8th Earl of Kingston, who was responsible for the building of the current Trevelyan-St George family home, once remarked that he felt the '[Llansteffan] Hall's sickeningly small, claustrophobic rooms an inconvenient stopping place on [his] way to London,' and referred to it as "The Welsh Cottage" freqently in his writings and vocal expostulations.

Little did he realise that this was going to be the future country seat of his descendents when trouble erupted in Ireland at the turn of the century, and that he was in fact, providing a safe haven for the Trevelyan-St Georges and the future heirs to the Earl of  Kingston title.

However, at the time, despite Llansteffan Hall being his idea, as well as being built to his design, George was not its most ardent fan; criticitsing its layout, proportions and declaring it of being of 'diselegant [sic.] proportions and ill-equipped execution' despite it being, both then and now, one of the largest private houses within the county of Carmarthenshire, and indeed Wales for that matter.  Elizabeth, his wife, known as "The Haughty Countess" amongst the ton of Ireland , and indeed, who gave the family surname the 'St-George' addition, only ever spent one night at Llansteffan Hall, despite it being ideally situated between their former seat, Castletown House in County Kildare, Ireland (pictured below), and the London residence on Cambridge Street, Pimlico.
