Fonds GB 0210 GLANSEVIN - Glansevin Estate Records,

The Lloyd family of Glansevin in the parish of Llangadog, Carmarthenshire, claimed descent from Ideo Gwyllt, earl of Desmond, who received the lordship of Llywel from Rhys ap Tewdwr (d. 1093) for his service against Bernard Newmarch. The surname Lloyd derives from Morgan Llwyd ap Cadwgan (fl. late 15-early 16 cent.). His great-grandson Gruffydd ap John is the first to be described as of 'Lan Sefin'. Glansevin was already a large dwelling in 1670, assessed for eight hearths.
It appears that the Lloyd family acquired other, smaller estates through marriage, or at least acquired some of the papers relating to these estates. Thus, Morgan Lloyd married Bridget, daughter of David Lloyd of Wern, Llanarth, Cardiganshire, and his wife Mary, daughter of Edward Pryse of Ystrad-ffin, Carmarthenshire. The Lloyds of Wern Newydd also owned the Mandinam estate, Llangadog, Carmarthenshire. Morgan Pryse Lloyd (c. 1758-1810) married Catherine only daughter of Pryse Jones of Glanhafren, Montgomeryshire. In 1826 Caroline Martha Lloyd (1788-1863), one of the daughters of Morgan Pryse Lloyd of Glansevin, married David Lloyd Harries (c. 1786-c1856) of Llandingat House, Llandovery, solicitor, heir to Maes Llydan in the parish of Llandingad and Pistyll Gwyn in the parish of Llansawel. He purchased Derry-odyn from Jane Edwards of the same, widow, in 1830.
Most of the Glansevin estate was sold after World War One, although the Lloyd family retained the house until World War Two. By 1985 Plas Glansevin had passed into new hands and become an hotel.
