Oh I see, didn't realise I was in Cymru. 

None of the links on the wikidata on https://www.openstreetmap.org/way/34493218 mention any "Bont Felindre" or "Pont Felindre" so I suspect it's just the user translating names themselves. 

If a survey yields no welsh/english name I'd suggest deleting them, or moving to loc_name if either name can be sourced but not verified on the ground.
