Ancestry, pedigree (7)
I believe the answer is:
lineage
I believe this clue is a double definition.
'ancestry' is the first definition.
(I know that ancestry can be written as lineage)
'pedigree' is the second definition.
(I know that pedigree can be written as lineage)
(Other definitions for lineage that I've seen before include "Genealogy" , "Descent (from an ancestor)" , "Pedigree, family tree" , "Ancestral line as seen in eagle" , "Line of descent or ancestry" .)
