Family __: genealogy chart (4)
I believe the answer is:
tree
I believe this is a double definition.
'family' is the first definition.
(I've seen this in another clue)
'genealogy chart' is the second definition.
(I've seen this in another clue)
(Other definitions for tree that I've seen before include "- Frog; - house" , "Plane or pine, for example?" , "Root-and-branch plant?" , "box, possibly" , "Recently named grouping of rogue states" .)
