Alexandra “of Sussex”

Currently watching. I love her character HOWEVER - British peerage still had family names… the Royal family uses their titles such as William Wales, etc. instead of Windsor, but if you are familiar with Downton Abbey which takes place during the same time, the Duke and Duchess of Grantham are the Crawley family. I know it was like a split second before she gave the name Dutton but did this bother anyone else?
