Brynna was originally called Brynna Gwynion but church records show that it was later shortened to Brynna from 1897 onwards.
Brynna is home to one primary school, Brynnau Primary School and is a feeder school for nearby Pencoed Comprehensive School. Welsh language provision is catered by Ysgol Gynradd Dolau in nearby Llanharan.
Opening in 1904 Brynnau Primary School celebrated its centenary year in 2004 with a number of events taking part in the village.
Brynna is also the name of an electoral ward to Rhondda Cynon Taf County Borough Council. It forms the western half of the Llanharan community (bordered to the west by Bridgend County Borough) and includes Brynna village, Bryncae and Llanilid. The ward elects a county councillor.
Brynna is also a community ward for Llanharan Community Council, electing six of the fourteen community councillors.
Social life in Brynna focuses around the last remaining pub in the village, The Mountain Hare. A previous pub the Eagle Inn is now closed. Brynna FC is the local football (soccer) team and it currently plays in the South Wales Bridgend premier division.
Brynna Woods and Llanharan Marsh have recently (2010) been taken over by the Wildlife Trust of South and West Wales and work is in progress to improve access for local people to enjoy this outstanding area for wildlife.
2013 will see major work by the Wildlife Trust to improve the habitat of Llanharan Marsh which is one of the few types of 'Valley Mire' habitats in Rhondda Cynon Taff. Fencing and subsequent grazing by local Welsh black cattle will help to bring back some of the natural flora and fauna that were previously there.
