Narrative
Margaret Wells says that this photo had Gwladys's notes on the back, and is of Margaret Price and Thomas Watkins in 1907 at 2, Cromwell Street, Merthyr Tydfil.
Actually, now that google streetview has been round here, it looks much more like Tudor Terrace, next door to Cromwell Street. But I can't make the stonework match up anywhere. In fact, it could be Brunswick Street, which is next door. The tops of the gateposts are different. Need to explore more.
Aha! No! It's 15 Norman Terrace. The stone blockwork matches up everywhere, even in the garden wall. Whoopee! Thank you, Streeview!
