ESTELLE ESTELLE CARNOCHAN, David's sister, the youngest of the seven children of James and Louisa, was their only daughter, and being pretty, blond, and very bright, she was the family pet. Her perennially delicate health—the early signs of tuberculosis—only added to the domestic affection. She was the particular favorite of her father, a charming and witty man, only intermittently faithful to his large, formidable, and adoring spouse, and after his premature death at forty-six, in 1907, Estelle had obligingly assumed the role of primary emotional support to her widowed mother, whom all New York regarded as a heroine, left as she was with all those sons to launch in the world. Why a heroine? Estelle sometimes asked this question of the shrewd little observer whom she artfully concealed behind an impassive front. Was Louisa Carnochan not possessed of robust health, an exuberant disposition, and a comfortable inheritance from a father who had bought farmland in northern Manhattan for nothing?
