Administrative/Biographical history: The Griffith family of Brynodol, in the parish of Tudweiliog, Caernarfonshire, is descended from Hugh, a younger son of Griffith John Griffith (fl. 1510) of Cefn Amwlch in the neighbouring parish of Penllech. Brynodol descended in the family until another Hugh Griffith, who was succeeded in turn by his two daughters Frances (d. 1711, osp) and Mary (alive 1719).
Mary sold the Brynodol estate to John Griffith (c. 1697-1764) of Caernarfon, a kinsman, a grandson of Gaenor, one of her father's sisters. John Griffith had already inherited a considerable purchased estate from his uncle, Hugh Griffith (d. 1717) of Caernarfon. The Brynodol estate then descended within the family until at least John Griffith Wynn Griffith (1849-1900, osp).
The Griffith family of Llanfair is entirely independent from the Griffith family of Brynodol. Maurice Griffith of Plas Newydd (also known as Llwyn y Moel or Porthamal) in the parish of Llanedwen, Anglesey, was the first to live at Llanfair (also known as Llanfair-is-gaer) in the parish of Llanfair-is-gaer, Caernarfonshire, in 1602, after Plas Newydd was alienated to Sir Henry Bagnall following the non-payment of a mortgage. Later in the seventeenth century the Llanfair estate devolved on the Wynn family of Taltreuddyn by the marriage of Mary Griffith, grand-daughter and sole heir of Maurice Griffith, with Edward Wynn. In 1748, the Llanfair, Taltreuddyn and Brynodol estates were united by the marriage of Mary Wynn, another sole heir, and Hugh Griffith of Brynodol.


Scope and content/abstract: Family and estate records of Griffith of Porthamal, Anglesey, and Llanfair, Caernarfonshire, Griffith of Brynodol, Caernarfonshire, and the associated families of Rowlands of Nant, Caernarfonshire, and Wynn of Taltreuddyn, Merionethshire. The estate records include rentals of the Llanfair estate, 1516-1669, the Brynodol estate, 1581-1751, the Cefnamwlch estate, 1630-1717, the Nant estate, 1702-1719, the Taltreuddyn estate, 1744-1848, the Llanfair and Brynodol estate, 1761-1832, and rentals from various other estates, 1615-1816; and deeds of the Porthamal and Llanfair estate, 1435-1673, the Brynodol (and later Llanfair and Brynodol) estate, 1564-1864, and the Taltreuddyn estate, 1664-1751.
