Forgive the viewers of Downton Abbey if they don’t know exactly where each love story ended up because, frankly, so much has happened. When the PBS phenomenon first launched in 2010 (15 years ago!), the Crawley family and the staff who kept their life in order were living in 1912 and the immediate aftermath of the sinking of the Titanic.

Fast forward a decade and a half, and after six seasons, two big-screen films (Downton Abbey and Downton Abbey: A New Era), and one more on the way (Downton Abbey: The Grand Finale), the characters are now braving the new decade of the 1930s, with all its progress and flagrant new takes on the order of society. In the last two decades, the family — upstairs and downstairs — has gone through its fair share of tragedy, joys, and, most importantly, significant others. It’s a wonder any of them have survived it all.
