How about a Downton Abbey-themed gift set consisting of the complete DVD box set, a Downton Abbey-inspired cookbook, and a Downton Abbey poster or decorative item to display on his wall? You could also consider purchasing him a Downton Abbey walking tour book and plan a trip to explore some of the filming locations together. Additionally, if he is a reader, you could find some books with a similar theme to Downton Abbey, such as Genevieve Gannon's 'The Forgotten Room' or Anne Perry's 'Cater Street Hangman.'
Or you can get him a star map with an important date you share.
