Mrs Tatcher actually was a baroness, not a baronetess. Different ranks but easily confused.
More fun facts: she held a Bachelor of Science in chemistry and worked for a time in developing soft serve ice cream!

Can I just point out the irony that, despite her image as being isolated, Margaret Thatcher was happily married, with two kids?
And that she was quite successful, including eventually being given a baronet?



EDIT: Nevermind, the writer actually does mention it...
