The paper presents a critical approach towards describing all Pomeranian culture multiple burials as family graves. Except for collective burial of a woman and a newborn, other combinations of age and sex of the dead buried together (in the same grave or even in the same urn) do not necessarily indicate family bonds between the deceased, at least not in the contemporary sense of the term. Providing arguments supporting the thesis that graves of various construction, including graves built of stone slabs (cists), surrounded by stones, or even devoid of any discernible surrounding, were filled with urns at the same time, the author believes that these multiple burials resulted from the custom of storing cremated bones, also known among some modern primitive communities. While stored, the urns might have been filled with remains of other dead people, which was noted during anthropological investigations of the Pomeranian culture urns. The presence of fragments of characteristic vessels (e.g. face urns) or even other pottery may evidence breaking of the original urn in which the remains of the deceased had been stored while waiting for the burial.
