Knud Slogvig, who, as we see, came in 1834, did not buy land but somewhat later returned east and in 1835 went back to Norway. There he married a sister of the slooper, Ole Olson Hetletvedt and, as we shall have occasion to note under causes of emigration, became largely instrumental in bringing about the emigration of 1836. Baldwin's _History of La Salle County_ also states, page 74, that Oliver Canuteson,[32] Oliver Knutson,[32] Christian Olson, and Ole Olson Hetletvedt came to the county in 1834, but the date seems to be uncertain. With regard to Christian Olson the fact seems rather to be that he came in 1836 or possibly not till 1837, while also Hetletvedt seems to be dated about two years too early here. Among those who came in 1836 according to apparently reliable records are: Ole Olson Hetletvedt and Gudmund Sandsberg. [32] Or are these two the same person? Relative to the founders of the Fox River Settlement, as that of La Salle County came to be called, I wish to add here the following facts of personal history: Gudmund Haugaas, one of the two first to record the purchase of land, had married Julia, the daughter of Thomas Madland, in Orleans County in 1827. She died in Rutland Township, La Salle County, in 1846 and he later married Caroline Hervig, a sister of Henrik Hervig (Harwick). He had ten children by his first wife. In Illinois he joined the Mormon Church and became an elder in that church, practicing medicine at the same time, and, it is said, with much success. He died of the cholera on the homestead near Norway in July, 1849; his widow, Caroline, survived him three years.[33] [33] Mrs. R. W. Bower of Sheridan, Illinois, is a daughter of Haugaas and his wife Caroline. Other children of his are Daniel Haugaas in Henderson, Iowa, and Mrs. Isabel Lewis, Emington, Illinois, and Thomas Haugaas. Jacob Slogvig married Serena, daughter of Thomas Madland, in March, 1831. He became one of the founders of the Norwegian settlement in Lee County, Iowa, in 1840 (see below), later went to California, where he died in May, 1864. The widow lived until about 1897. Some time before her death she had been living at the home of her son, Andrew J. Anderson, at San Diego, California.
