Love child for one backed First Nations leader (8)

I believe the answer is:

geronimo

I'm a little stuck... Click here to teach me more about this clue!

'nations leader' is the definition.
'geronimo' can be an answer for 'leader' (I have seen 'Brave leader' mean 'geronimo' so perhaps 'leader' could also mean 'geronimo'). I'm not sure about the 'nations' bit.

'love child for one backed' is the wordplay.
'love' becomes 'o' (love means zero in tennis).
'child' becomes 'minor' (synonyms).
'for one' becomes 'eg' (both can mean 'for example').
'backed' says the letters should be written in reverse.
'o'+'minor'+'eg'='ominoreg'
'ominoreg' reversed gives 'GERONIMO'.

'first' acts as a link.
