We are very indebted to the Llantrisant and District Local History Society for their diligence in researching and presenting the history of Llantrisant and the surrounding area including Pentyrch. Their researches go back to before the Norman Conquest and show the ownership of land in the area. We are particularly grateful to D.Barry Davies for carrying out much of this work.
The work is recorded in over 100 papers many of which ar relevant to this area. Some of these papers are detailed below.
