More recently, Ms. Botín was based in London, where she was in charge of the bank’s British operations. In addition to his daughter Ana Patricia, Mr. Botín’s survivors include his wife, Paloma O’Shea, a classical pianist, patron of the arts and founder of the Queen Sofía College of Music in Madrid; and five other children, Carmen, Emilio, Carolina, Paloma and Francisco Javier.
