The family of Peisistratos did not indulge in strikingly uncommon names but it is noteworthy that all but one of them also appear in Chios. Neleus or Neileus (e.g. c. 150a, SEG xvii 381 A 1.2), Hippokrates (c. 420a, RE s.n. 14), Hipparchos {s. Ia, BSA lxi [1966] 199 no. 3.15), Heges[istratos?] (e.g. s. IVa, NC xv [1915] 430), Peisistratos, Hippias and Thessalos (see below): only Iophon is certainly missing. Their occurrences cover many centuries and no long filiations can be established, nor is there any positive argument that they all belonged to the same family, but for the late fourth and third centuries there is a hint. Chian social units had a family-based molecular structure. A catalogue of one of them gives us about 70 names c. 300a with an average of two additions p.a. thereafter (BSA lv [i960] 181–7 = SEG xix 580). On it there is a Hippias of the later fourth (father of the named member) and a Thessalos of the later third century. At least one Hippias appears on coins of the later fourth (NC xv [ 1915] 430) and another (or the same) on a subscription list of the mid third as father of the subscriber (SEG xix 578.12). A Chian Peisistratos dedicated in Rhodes in the second century (IG xii.i 113), a Peisistratos son of Peisistratos made a patriotic subscription in the later third (BCH xxxvii [1913] no. 27. 18—19), a Chian Peisistratos, grandson of Peisistratos, is given proxenia at Delos in the mid third or a little earlier (IG xi.4 598), a Peisistratos put his name on coins belonging to the same chronological group as those of Hippias (NC xv[i9i5]430). That the Hippias-group and the Peisistratos-group were somehow related is put beyond doubt by the name which one fourth-century Hippias and one fourth-century Peisistratos gave to their sons.
