The Society was formed in 1971 on the initiative of Mr Roy Denning to research and discuss the history of the area. After an uncertain start, membership stabilized at around 50. This has increased over the years and now stands at around 130 of whom half attend our meetings while most of the remainder are scattered widely around the UK.
Membership is open to all with an interest in the history of the ancient Borough, the even more ancient Parish and all those adjacent parishes that were, historically, part of the southern half of the Welsh lordships of Meisgyn and Glynrhondda. This wide interest involves an overlap of membership with the neighbouring historical societies of Pontypridd and Pentyrch. Also, due to work that has been done on local families for the 17th and 18th centuries, there is an overlap with the Glamorgan Family History Society. Members are also encouraged to join the Glamorgan History Society.
