Family internally raised capital (4)
I believe the answer is:
lima
'capital' is the definition.
(capital of Peru)
'family internally raised' is the wordplay.
'internally' indicates a hidden word.
'raised' says the letters should be written backwards.
'amil' can be found hidden inside 'family'.
'amil' in reverse letter order is 'LIMA'.
(Other definitions for lima that I've seen before include "city (like 22)" , "Kind of bean" , "Edible bean; capital city" , "Mail to Peru'd capital" , "Mail to capital of Peru" .)
