Landowner from the old country (6)
I believe the answer is:
yeoman
'landowner' is the definition.
(yeoman is a kind of landowner)
'the old country' is the wordplay.
'the old' becomes 'ye' (resembles a historical spelling of 'the').
'country' becomes 'oman' (Oman is an example).
'ye'+'oman'='YEOMAN'
'from' is the link.
(Other definitions for yeoman that I've seen before include "Farming freeholder of old" , "One guarding" , "Countryman" , "Petty officer" , "Officer in royal household or a small farmer" .)
