Hungarian cemeteries in an effort to detect familial structure. Different ethnic groups buried in separate areas dominated the spatial pattern in two cemeteries, leaving insufficient power to test for familial patterns. In a third, ethnically homogeneous cemetery, no evidence of familial structure was found. A simulation showed that familial structure could readily be detected by the methods applied when it exists in an ethnically homogeneous population. The spatial autocorrelation methods employed would have detected the ethnic diversity in the two cemeteries containing graves from different populations, even in the absence of archaeological information to that effect. A restricted randomization procedure was developed to test two alternative hypotheses concerning the ethnic designations of the occupants of the cemetery at Szentendre. As a result of this test, the hypothesis that graves located in a rough circle (putative Lombards) differ serologically from those located at the periphery (putative nonLombards) is strongly preferred over a second hypothesis based on grave goods which would imply spatially random placement of the graves of the two ethnic units.
