This 2016 standalone prequel episode "Young Hyacinth", which might have been intended for a back-door pilot leading to a prequel series, offers more of the origins of Hyacinth's mindset. The family surname is finally revealed to be "Walton." In the early 1950s, Hyacinth Walton works as a domestic servant for the Cooper-Smiths by day and lives in a small canal cottage with her alcoholic Daddy and her three younger sisters, Violet, Daisy, and Rose. Impressed by her eccentric employers, Hyacinth vows to escape her poor background and enter the elegant world of the upper class, leading to her ongoing behaviour seen in "Keeping up Appearances" of "trying to climb the social ladder". Presumably, if the episode had become a series, it would finally have officially revealed just exactly how and why Hyacinth and Richard met and married, which continues to cause much debate and many theories.
