Bledri ap Cydifor (fl. 1116-30) was a Welsh chieftain. According to a record in the 'Cartulary of Carmarthen Priory' he was a ‘Latemeri’ (interpreter), which would suggest that he (having the skills to negotiate with invaders) was a notable Welshman in the area. During the Welsh revolt of 1116 it is believed that the Normans entrusted him with the castle of Robert Courtemayn, near Carmarthen. His descendants were also prominent landowners, and may be traced to Cil Sant, Pwll Dyfach, Motlysgwm, and Picton.
