From the History of Llangurig by BY EDWARD HAMER, Esq., and H. W. LLOYD, Esq. 1875

“ Niniaf, the eldest, was ancestor of the Jones-Parrys of Madryn Park, and Llwyn-Onn; the present head of this family, Thomas Love Dimcombe Jones-Parry, of Madryn, Esq., is Chief of the descendants of Cynwrig ab Rhiwallon. When the old church at Wrexham was destroyed by fire in 1457 and the Pope gave instructions to have it rebuilt as it now stands, the Llwyn-Onn family were the first to respond to the injunctions of the Holy Father; their teams carried the first loads of stone for the restoration of the present beautiful edifice, and it is a very curious fact that this family alone, of all the once numerous descendants of Cynwrig ab Rhiwallon possess their lands by an unbroken male descent from Cadell Deymllwg, — "They who honour me I will honour," saith the Lord.

The other families who descend from Niniaf are the Lloyds of Llwyn-y-Cnotiau; the Robertses of Hafod-y-Bwch; the Joneses of Croes-Foel, Edward Jones of Plas-Cadwgan, who was attainted and executed in 1586; Edwards of Sealyham, and Lord Kensington; Erddig of Erddig; Traffords of Esclusham; Goronwy ab Hwfa of Hafod-y-Wem, now represented by Philip Davies Cooke of Hafod-y-Wem and Owston, Esq.; Madog yr Athraw ab Hwfa,of Plâs Madog and Erbistog; the Bershams of Bersham; the Wynns of Gerwynfawr; the Eytons of Eyton-Uchaf, and the Sontleys, of Sontley”
