Fonds consists of a history of the Swanson family as well as photographs and drawings of members of the Swanson family and a few locations. Fonds contains two series: Family history and Photographs and drawings.

Series consists of a photocopy of the handwritten family history of Christian and Julia Swanson. It was likely written by either Florence or Ida Swanson ca. or in 1986. A portion of it was originally by John William Swanson, Christian and Julia's eldest son, in 1958 but was likely recopied to add to this history.

Series consists of 14 photographs and 4 drawings of members of the Swanson family. Most photographs are labelled either on the photograph or had a paper label with it in the original photo album. Drawings are of, presumably, Christian Swanson's parents and Julia (Johanneson) Swanson's parents. Also includes photographs of the paternal and maternal grandparents' homes in Tännäs, Sweden.
