Ym mhentref bychan Pennon tua milltir o Lancarfan ym Mro Morgannwg saif Bryn Iolo. Yma, dros ddwy ganrif a hanner yn ôl, ganed Iolo Morganwg (Edward Williams). Ar hyn o bryd, does dim byd i gofnodi’r ffaith nac i gysylltu'r lleoliad ag un o feibion pwysicaf a mwyaf creadigol ein cenedl.

In the hamlet of Pennon a mile outside Llancarfan in the Vale of Glamorgan stands Bryn Iolo. This is where, over two and a half centuries ago, Iolo Morganwg (Edward Williams) was born. There is at present nothing to proclaim the fact or the village connection with one of Wales’ most important and creative sons.
