Harry and Meghan are NOT "commoners" now. A commoner is someone who is:
a) not the monarch
b) not a bishop or above in the Church of England (Lords Spiritual)
c) not a secular peer (Lords Temporal)
(thread)
I know, it's both mind-blowing and confusing.
In order, the titles are Duke, Marquess, Earl, Viscount, Baron.
Only for the line of succession to the throne, not titles of peerage. :(
However, Harry (still 6th in line) and Meghan are NOT commoners.
