Administrative / Biographical History

The founder of the family fortune was Rice Thomas (d. 1577), son of Sir William Thomas of Llangathen, Carmarthenshire, who established the Caernarfonshire base of the family. It was his grandson, Sir William Thomas (1572-1643) who purchased the Coed Helen estate, mainly in and around the town of Caernarfon. On the death of Sir William's second son, Gruffydd, without issue in 1676, the estate passed to Gruffydd's cousin, John Thomas. The estate then descended in the male line until Rice Thomas (1771-1850), who died without issue. The estate passed to his sister Elizabeth, who married Sir William Buckeley Hughes (1766-1836) in 1792. The last recorded occupier of the estate was Lloyd Edward Bulkeley Hughes (b. 1870), whose eldest son was Rice John Lloyd Hughes (b. 1915). The family also acquired the Glascoed estate in Llanddeiniolen, Caernarfonshire, following the marriage of Rice Thomas and Gaynor Wynne, heiress of Owen Wynne in 1717. She died in 1719.
