Another individual (sample I7640) in the study was found positive for S883 (a Z2185 equivalent) which is upstream from L1066.  The remains from the Middle Bronze Age and radiocarbon dated to the 14th century BC was from Clay Farm in Cambridgeshire, England. Sample I7640 was a no-call for L1066, so could have been positive, we just don't know. See http://www.trumpingtonlocalhistorygroup.org/meetings_0411.html
