I have been following your clues Hugo, and I travelled up and down Broad St. in Junction and Mostyn Broadway (on Google Streetmaps!) after yesterdays hint but have found nothing. The only link I have found is two villages in Shropshire named Porth-y-Waen and Treflach just outside Oswestry (74.3 miles away, and just over the English-Welsh border), which have a connecting road a road named Blodwel Bank, the same name as the old Blodwel Home in Junction.
