On the North Forum you give the reseason today for William H Weston not inheriting an Earldom as due to a clerical error, your message on this board says due to a political error. Whatever neither situation would deprive an heir to an Earldom.
I said this on the North board re the North Claim:-
I am pretty certain there is no substance to your great uncle's story which with due respect has all the hallmarks of a family myth, of which there are many.
Lord Frederick North had two sisters namely Lucy who died a few days after birth in 1734, and I have seen evidence that was so, and a step-sister Lady Louisa North 1736-1798, she married John Peyto Verney, 14th Baron Willoughby de Broke. They had 3 children, two sons who were respectively to become the 15th and 16th Barons Willoughby de Broke and a daughter Louisa whose son succeeded the title of as 17th Baron Willoughby de Broke.
I am not aware of a relationship connection with your Weston ancestor with the above North and Verney families of the period mentioned above, and frankly I would be truly amazed if there was.
