| AdminHistory | The original Cilglasslyn and Bryneisteddfod stock were connected with the parish for between 300 and 400 years, and appear to have traced their descent through a branch of the Conwys of Llys Euryn, who at one time owned much land at Glan Conwy, and through Robin ap Grufydd Goch of Graianllyn, Ednyfed Fychan and Marchudd ap Cynan. |
