Wisconsin law required counties to register birth events with state officials starting in 1852, but the law was not strictly enforced until roughly 1880. Most records date from 1880 or later. It is possible that some records only exist at the county level and are not in our state-level collection. We do not have birth records after September 30, 1907.
