Graves in the Old Churchyard
 

4 tombs, dated 1662 and 1681 under the east window  belong to the Williams family of Blaen-Baglan. 2 of the stones  have armorial bearings including three chevrons, denoting descent from Iestyn ap Gwrgan, who in 1090, was the Lord of Morgannwg (Glamorgan) when the Normans arrived.  There is also a double crest of Paschal Lamb showing links to the Crusaders and the cockerel which, some say,  was used by the Knights Templar.

​

Mae 4 beddrod, dyddiedig 1662 a 1681 o dan y ffenestr ddwyreiniol yn perthyn i deulu Williams o Flaenbaglan. Mae arfbeisiau ar 2 o’r beddrodau sy’n cynnwys tri sieffrwn, sy'n dynodi disgynyddiaeth o Iestyn ap Gwrgan, a oedd yn Arglwydd Morgannwg ym 1090, pan gyrhaeddodd y Normaniaid. Mae hefyd arfbais ddwbl o Oen y Pasg sy'n dangos cysylltiadau â'r croesgadwyr a'r ceiliog a ddefnyddiwyd gan Farchogion y Deml.
