The County Clerk's office contains a wealth of materials for both the genealogist and general researcher. Among the records you may find useful are naturalizations, marriage certificates (duplicates of forms filed with the local town or village dating from 1908 to 1931), census records (1850, 1860, 1880, and 1910 federal and 1835 to 1925 state), school records (mostly financial reports dating from 1829 through 1950), incorporations and business documents, Tuttle's records - a collection of information compiled by one-time Madison County historian William H. Tuttle (Veteran and Burial, 10,000 Names, Miscellaneous), deeds, and mortgages. Much of this information can be found online under the Historian's pages of the county website.
Please note: birth, death, and marriage certificates (exception noted) are not filed with the County Clerk's office. Please contact the town, village, or city where the event occurred for these records.
