Alternative Name: Treffilip
Morphology: tref + the name Philip
Phonetic: trev-phillip
Named after Nehemiah Phillips (1845-1929), a major stakeholder in the Powell Duffryn Steam Coal Company Ltd and a colliery manager, county councillor and an active Baptist preacher. The Welsh name is one of only a few examples in the county borough where an original English-only name has been translated, in this case to the extent of having accommodated the name Phillip into Welsh. This happens frequently from Welsh-to-English in place names, but is rarely seen in reverse.
