Tax Records

Wisconsin tax records complement land records and can be used to supplement the years between censuses. Because only persons who owned property or other items that could be taxed were listed, some residents were not included in tax lists. There may also be gaps of several years in the tax records. For more information see the Wiki page, Wisconsin Taxation.

Vital Records

Vital records consist of birth, death, marriage and divorce records. Most counties started keeping records in the 1870s. In 1907, the counties began sending copies to the state.

For pre-1907 births, deaths, and marriages, search the Wisconsin Genealogy Index.
