Lineage, ancestry (8)
I believe the answer is:
pedigree
I believe this is a double definition.
'lineage' is the first definition.
(pedigree is a kind of lineage)
'ancestry' is the second definition.
(pedigree is a kind of ancestry)
(Other definitions for pedigree that I've seen before include "Line of decent or ancestry" , "Lineage of purebred animal" , "Of animals, recorded line of descent" , "List of ancestors" , "(Pure) ancestry" .)
