When shipped, I greet a display of ancestry (8)
I believe the answer is:
pedigree
'ancestry' is the definition.
(I know that pedigree is a type of ancestry)
'when shipped i greet a display' is the wordplay.
'a display' indicates a hidden word (I've seen 'displays' mean this).
'PEDIGREE' is hidden in the letters of 'when shipped i greet'.
'of' is the link.
(Other definitions for pedigree that I've seen before include "Lineage of purebred animal" , "High-class" , "Blood line" , "Breeding; descent" , "Record of descent" .)
