It was also known as Lower Llanfihangel y Creuddyn, Lower Llanfihangel y Croyddin and Lower Llanfihangel y Croyddyn. This parish is situated on the rivers Ystwyth, Mynach and Rheidol and intersected by various other streams. An ancient parish was a village or group of villages or hamlets and the adjacent lands. Originally they held ecclesiastical functions, but from the sixteenth century onwards they also acquired civil roles. The parish may have been established as an ecclesiastical parish. Originally a medieval administrative unit, after 1597 ecclesiastical units acquired civil functions with the Elizabethan Poor Laws, which made the parishes responsible for welfare. The civil function was exercised through vestry meetings which administered the Poor Law and were responsible for local roads and bridges.
