Accrual consists of two scrapbooks (2003-2005 and 2006-2009) documenting the activities of the Concordia Club.

Fonds consists of material relating to descendants of Johann Christoph and Anna Elizabeth Schneider, their families, friends and activities. It also contains genealogical information about the Schneider and Ahrens family origins in Germany and relatives there. Includes clippings, correspondence, ephemera, films, manuscripts, photographs, slides, etc.

The majority of the archives of the Concordia Club were destroyed either as a result of the ransacking of the club by the 118th Batallion in 1916, or as a result of the fire of Nov. 17, 1971. As a result the earliest records of Concordia have largely been lost forever. A very small number of items can be traced back to the Concordia Male Choir (1873-1914). These take the form of two items of correspondence, programs for the "Sängerfests", clippings, and photographs. A small number of archival records also can be found which belonged to the "Deutscher Club, Kitchener" (1925-1930), and include a set of house rules, letters patent, and photographs. Some records from the 1930s have also been preserved to this day, and include artifacts, clippings, legal documents, a membership list, photographs, and programs of events. However, the majority of the materials date from the 1950s onwards. These materials document the history of the Concordia Club since the 1950s, and include artifacts, audiovisual material, clippings, correspondence, ephemera, financial records, legal documents, membership records, minutes of meetings, photographs, publications, and scrapbooks.

Accounts of the German Baptist Church from 1894-1923. The volume contains lists of members, including many familiar local names, and statements of accounts. It also contains documents relating to the Benton St. Baptist Church, including annual reports and financial statements ca. 1919-1930.

Like many other Kitchener natives, E.B. Dunke seems to have purchased land in Saskatchewan, documented by one file of correspondence.

Edwin Dunke was probably the proprietor, or part owner, of Dunke and Co., a grocery store at 35 King. St. E. between Queen and Benton Streets. The "day books" of this store, complete with customers' names, purchases and store inventories reveal the daily lives, diets and purchasing patterns of local families and individuals from 1896 to 1930.
