Lineage, ancestry (8)
I believe the answer is:
pedigree
I believe this is a double definition.
'lineage' is the first definition.
(I know that lineage can be written as pedigree)
'ancestry' is the second definition.
(I know that ancestry can be written as pedigree)
(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" .)
