"When your grandmother and I visited Bledlow we went to "The Hall" where she lived as "The Squire's Lady," and I saw the room where your father was born, the church where he was christened, and we came across some of your grandmother's old servants, who still addressed her as 'My Lady.' The squire was much older and he used to ride on horseback over all his domains... but one day he was thrown over the saddle, hurt himself in some way, was sent on a sailing vessel to recruit [recoup?], died and was buried at sea, and some months later your father was born, and later your grandmother sold out her possessions in Bledlow, and went back to her people in London. That's the story as I remember hearing it."
