Eugene Matthaus Unterreiner was the son of Anton Unterreiner and Regina Schott. He was married twice. The first to Barbara Schneider on May 15, 1853 in Apple Creek, Perry County, Missouri. Eugene and Barbara had 2 children; Theodore and Charles.
After the death of his first wife, Barbara, Eugene married Catherine "Kate" Schulte, July 26, 1865, in Madison County, Missouri. There were at least 3 children from this marriage: Mary Ellen (1869- 1921 Married John Joseph Duvic, 1868-1954), Alexander (1873-1901), and Emma (1873-1964 Married William Pelletier).
Catherine Schulte was born about 1846 and died sometime after 1885 possibly in St. Louis, Missouri. Catherine is possibly a daughter of Antone Schulte and Antionette Willeke. Catherine was listed on the 1876 state census for Madison County, Missouri, along with her and Eugene's 3 children plus Eugene's 2 children from his previous marriage to Barbara Schneider (Theodore and Charles). She and her 3 children were listed on the 1880 federal census for St. Louis, Missouri (surname is spelled Underiner on this census). She is also listed on page 566 in the St. Louis City Directory for 1884.
