One gets a quick picture of Lord Chesterfield and his son from this snippet of conversation from Boswell's "Life of Johnson". It is the son that is referred to in Sir Walter Scott's "St. Ronan's Well" (his own son being less than 10 at the time the novel is set - probably 1809-1812 according to E.U.'s Walter Scott archive). St. Ronan's Well was Scott's unsuccessful foray into the realm of domestic manners:
'Shall I go with you, my dear?" said Lady Penelope.
"No—I have too great a soul for that—I think some of them are lions only as far as the hide is concerned."
"But why would you go so soon, Clara?"
"Because my errand is finished—have I not invited you and yours? and would not Lord Chesterfield himself allow I have done the polite thing?"
