Lady Sun
Kong Lingyi had a total of two wives and two concubines. His first wife, Lady Sun (孫氏), was the daughter of Sun Yuwen (孫毓汶) (1833 - 1899), an Imperial Envoy, and she was one year older than Kong. Lady Sun's grandfather, Sun Ruizhen (孫瑞珍) (1783–1858), was a scholar and official during the Guangxu Emperor's reign. Kong and Lady Sun married in 1888, but she died of illness without issue in 1899, aged 28. Kong's first concubine, Lady Feng, similarly did not have any children, and she died in 1928. Kong's second wife, Tao Wenpu, (陶文譜, known as "Lady Tao" [陶氏]), was the youngest daughter of Tao Shiyun (陶式鋆), Magistrate of Daming Prefecture, and Kong married her in 1905; compared with Lady Sun, though Tao family was rich at the time, it wasn't as prominent as Sun family. She bore Kong one son who died at the age of three years. Lady Tao was described as a petty, jealous woman who mistreated Kung Te-cheng's mother, Kong Lingyi's second concubine Wang Baocui (王寶翠) (1894 - Qufu, 11 March 1920), the daughter of a peasant from Zunhua County, Hebei.
