Family folklore is the branch of folkloristics concerned with the study and use of folklore and traditional culture transmitted within an individual family group. This includes craft goods produced by family members or memorabilia that have been saved as reminders of family events. It includes family photos, photo albums, along with bundles of other pages held for posterity such as certificates, letters, journals, notes, and shopping lists. Family sayings and stories which recount true events are retold as a means of maintaining a common family identity. Family customs are performed, modified, sometimes forgotten, created or resurrected with great frequency. Each time the result is to define and solidify the perception of the family as unique.
