BGSU Archival Collections

The BGSU Center for Archival Collections in Bowling Green holds microfilmed Williams County records. This is one of the best sources for northwest Ohio genealogy. Their Williams County holdings include birth records from 1867 to 1943, death records from the same period, marriage records from 1824 to 1941, naturalization records from 1836 to 1929, and will records from 1809 to 1911.

They also have civil dockets from 1859 to 1887, a general index from 1868 to 1924, guardian records from 1878, records of ministers' licenses from 1872 to 1937, and commissioners' journals from 1859 to 1970. The Court of Common Pleas journals go back to 1824. These microfilm reels are available for on-site viewing at the BGSU Jerome Library in Bowling Green. This collection makes the BGSU archives an essential stop for serious Williams County research. The will records alone cover 1809 to 1911 on five reels of microfilm, giving you access to over a century of estate records without visiting the courthouse.

BGSU is about an hour drive from Bryan, but the trip is well worth it for the range of records available. The center staff can help you find the right reels and work through the indexes. If you cannot visit in person, check if the records you need have been digitized and posted online through FamilySearch or other databases.
