Hello Charlotte and John,
Great to hear from both of you!
Alfred's son, Lawrence, who emigrated to Canada (where I live) was my grandfather. Thanks for the information about David Megson!
Re. the Swan Arcade shop. We have family documents dated past the turn of the century that mention the business--but none that I've seen, or remember seeing, are specific about how long the shop was in existence. Having said that, I recently purchased a copy of an antiquarian book titled, "Ye Scenes of Olde Bradforde--Strolls Through Some Old Highways and Streets Being an Itinerary Catalogue of Mr. Alfred Megson's Collection of One Hundred Views of By-gone Bradford". Once the book arrives, I'll look through it to see if it includes any biographical information about the Swan Arcade shop that you may find useful, Charlotte. I purchased the book online from The Idle Booksellers, who specialize in books about Yorkshire.
Best,
Susan Megson
