They learned this important fact by practice from early childhood. With the advent of the monogamous family this was gradually forgotten. The gentile name created a pedigree by the side of which that of the monogamous family seemed insignificant. This name had now the function of preserving the memory of the common descent of its bearers. But the pedigree of the gens went so far back that the gentiles could no longer actually ascertain their mutual kinship, except in a limited number of more recent common ancestors. The name itself was the proof of a common descent and sufficed always except in cases of adoption. To actually dispute all kinship between gentiles after the manner of Grote and Niebuhr, who thus transform the gens into a purely hypothetical and fictitious creation of the brain, is indeed worthy of "ideal" scientists, that is book worms. Because the relation of the generations, especially on the advent of monogamy, is removed to the far distance, and the reality of the past seems reflected in phantastic imaginations, therefore the brave old Philistines concluded and conclude that the imaginary pedigree created real gentes!"
The phratry was, as among the Americans, a mother-gens comprising several daughter gentes, and often traced them all to the same ancestor. According to Grote "all contemporaneous members of the phratry of Hekataeos were descendants in the sixteenth degree of one and the same divine ancestor. All the gentes of this phratry were therefore literally brother gentes.
