As far as neolithic ancestry is concerned, aample ROC001 has high ANF and low WSH like most Mycenaean samples do, but it also has WHG which Mycenaean Greece lacked.
IMO the sample is probably related to profiles from LBA-EIA Sicily who just like Mycenaeans retained high EEF continuity.
One of the samples who have enough coverage seems to look like Mycenaeans just with more WHG admixture.
