Charles Dickens had family links to Shifnall that can be proven via historic records https://www.familysearch.org/tree/person/details/MMMV-NZB One of the descendants Tne Molinueuxs of Albrighton were into making Naval Brasses. Now one of the names in The Old Curiosity Shop is Brass. Dickens also stayed in Albrighton.
My grandmother was a housekeeper at Tong castle so am keep to prove the link myself. I do have a family link to the Perrys in Claverley but I stumble on the many John Perrys there.
I think the guy may have an agenda and an interest in the shop in London, which has no business being on the wikipedia page.
