Research tip
Idaho began statewide registration of births and deaths in 1911. Before 1863 its land was part of Oregon and Washington territories (the east also of Nebraska and Dakota territories), and some early settlers in the southeast recorded events in Cache County, Utah, thinking they lived there.
