Quick to make friends in Ealing (6)

I believe the answer is:
genial
'quick' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?
'make friends in ealing' is the wordplay.
'ealing' can be anagrammed to 'GENIAL'.
Though, I am not clear how this is indicated.
'to' is the link.
Can you help me to learn more?
(Other definitions for genial that I've seen before include "Affable in Ealing" , "Cordial" , "'Cheerful, friendly, sociable (6)'" , "Angel I found being affable" , "Amiable - linage (anag)" .)
