A daughter church St Tyfaelog's, parish church of Pontlottyn (NPRN 13280) was established as a Mission Church in the hamlet of Troedrhiwfuwch in 1874-5. Dedicated to St. Teilo, it was located on the west side of High Street. The church was demolished, together with most of the hamlet, in the 1980s. The plan of the church as portrayed on early maps suggests it was entered by a porch on the west gable, and had organ chamber and vestry flanking the chancel.
