Archaeologists found the mummies in the foundations of a row of unusual Bronze Age terraced roundhouses. But after being radiocarbon dated, all were found to have died between 300 and 500 years before the houses were built, meaning they had been kept above ground for some time by their descendants.
The results of the DNA work on the Cladh Hallan mummies will feature on the latest series of Digging For Britain on BBC Two in September.
