I've just got to the bit in Fanny Burney's Evelina where our eponymous heroine visit a grand house on Clifton Hill during her stay in Hotwells. It was interesting to wonder if it could be any of the places I passed in my lunchtime jaunt, which took in both Clifton Hill and Lower Clifton Hill.
From Evelina (1778):
"Yes, Ma'am; his Lordship is coming with her. I have had certain information. They are to be at the Honourable Mrs. Beaumont's. She is a relation of my Lord's, and has a very fine house upon Clifton Hill."
