The Wright brothers were two of seven children born to Milton Wright (1828–1917), of English and Dutch ancestry, and Susan Catherine Koerner (1831–1889), of German and Swiss ancestry. Wilbur was born near Millville, Indiana, in 1867; Orville in Dayton, Ohio, in 1871. The brothers never married. The other Wright siblings were named Reuchlin (1861–1920), Lorin (1862–1939), Katharine (1874–1929), and twins Otis and Ida (born 1870, died in infancy). In elementary school, Orville was given to mischief and was once expelled.
