Hey guys,
I'm writing a novel with British, French and other European aristocrats. I noticed that in French everyone always used, "de" which would translate, "of that." Because to be Lord you have to own a land. I wonder why Lord Byron and other Lords chose to the drop the "of the" from their name.
The only reputable free guide I can find to this is here: https://www.parliament.uk/business/lords/whos-in-the-house-of-lords/how-to-address-a-lord/ which is current but hasn't changed in at least two centuries.
Byron is a name not a place, so "Lord Byron" is the correct form of address. Generally nobody is ever addressed as "Lord of X" much less "Lord of the X".
A Duke is addressed as "The Duke of [Place]" or "His Grace the Duke of [Place]". Pretty much all other members of the peerage (Barons, Baronets, Viscounts) are addressed as "Lord [Surname]". Earls are variously addressed as "Lord [Place]", or "The Right Honourable [Surname], Earl of [Place]".
Byron was a baron, so would just have been Lord Byron.
