A daughter, Astrid Susanto, deputy chair of the People's Representative Council's Commission I, died in 2006. He is survived by three other daughters -- Sunaryati Hartono, vice chairman of the National Ombudsman Commission of Indonesia; Sunardien, an economist; and Wuryastuti Sunario, managing director of the Indonesian Tourism Promotion Board—and a son, Irawan Sunario. A granddaughter, Maya Sunario, is a committee member of the Indonesian-Irish Association since 2003  and is based in Dublin, Ireland. Her daughter Kira Sunario Lynch is an international student in BINUS International, Jakarta. Soenario's siblings included Sunarjo Sastrowardoyo, an elementary school teacher; Sukanti Suryochondro, an instructor in women's studies at the University of Indonesia; Subekti Sastrowardojo, who died in infancy during the 1918 influenza pandemic; Suryono Sastrowardoyo, a career diplomat whose posts included Singapore, Italy, the United States and Poland; Sumarsono Sastrowardoyo, a physician, surgeon and memoirist; Subagio Sastrowardoyo, a noted poet and academic; and Sumarsongko H. Sastrowardoyo, of the staff of the Consulate General of Indonesia in New York City. He is a first cousin, once removed, of Nugroho Wisnumurti, who was Indonesia's Permanent Representative to the United Nations and Other International Organizations in Geneva, Switzerland from 2000 to 2004. Two nephews, Rahadyan Sastrowardoyo and Hartriono B. Sastrowardoyo, are U.S.-based journalists (the latter for The Asbury Park Press). The actress Dian Sastrowardoyo is a grandniece. Like many Javanese, Mr. Soenario had just one name, though the practice of a given name plus a surname chosen after higher education had begun with his father in 1896. In the old Dutch spelling, the family name had been spelled "Sastrowardojo" but, even prior to the spelling reform in Indonesia in 1972, some members had changed the "j" to a "y"—and one brother, Sudibbyo, spelled the name "Sastrowardhoyo," reflecting the aspirant "d". The family name was derived from "sastra" (Sanskrit, 'writings') and "wardaya" (Sanskrit, 'heart'), so literally meant "writings of the heart."
