2. Pedigree, genealogy refer to an account of ancestry. A pedigree is a table or chart recording a line of ancestors, either of persons or (more especially) of animals, as horses, cattle, and dogs; in the case of animals, such a table is used as proof of superior qualities: a detailed pedigree. A genealogy is an account of the descent of a person or family traced through a series of generations, usually from the first known ancestor: a genealogy that includes a king.
c.1410, "genealogical table or chart," from Anglo-Fr. pe de gru, a variant of O.Fr. pied de gru "foot of a crane," from L. pedem "foot" + gruem (nom. grus) "crane," cognate with Gk. geranos, O.E. cran, see crane). On old manuscripts, "descent" was indicated by a forked sign resembling the branching lines of a genealogical chart; the sign also happened to look like a bird's footprint. Form infl. in M.E. by association with degree. Meaning "ancestral line" is c.1440; of animals, 1608.
