The majority of the individuals from the extended Shellens family are unidentified, though some photographs do provide identifications on their versos. There is also a small number of photographs pertaining to Michael Shellens's seafaring and real estate careers. Several different types of photographic media are contained in this series, including cartes-de-visite, cabinet cards, and tintypes.
