Osage County Cousins is a family genealogy website created and maintained by Larry G. Banks. It documents the Banks, Parson, Kemple, Mantle, Monroe, Redden, and Butler families in Missouri, with a searchable family tree containing information on more than 13,000 relatives. Visitors can search by first name, last name, or surname, browse family records, and generate charts showing an individual’s ancestors or descendants. Public browsing is available without an account, while details about living or private individuals are withheld. Registered family members may request full access to additional information.

The site also offers a range of genealogical resources, including photographs, documents, cemetery and headstone records, census data, city directories, obituaries, marriage and military records, wills and probate materials, and family histories. Other features include a calendar of dates and anniversaries, place and source listings, DNA test information, and sections highlighting new or particularly sought-after records. Through these tools, Osage County Cousins helps relatives and researchers explore family connections and historical materials.
