Thanks, Sian & Carole. I did think that there was possibly some confusion over Wind Street, but it seems it's just a coincidence that Fagg chose Wind Street in both Swansea & Neath. The other coincicence is that Elizabeth Davies was in Wind Street, Neath when Filmer Fagg printed her verses in Wind Street, Swansea.
I suppose most of the towns round the bay would have a Wind Street.
