Sporcle has a timed quiz going on to see how many of the English royal dynasties you can name. Some of them may be self evident, whilst others may be hidden well within your mind. I got stuck with one remaining for what felt like ages, but eventually perservered.
It’s quite entertaining, and at most takes two minutes, so I suggest you give it a go and leave a comment with how you did. 🙂
Good luck.
