Turkish officer, Priam's nephew and Electra's father (9)

I believe the answer is:

agamemnon

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

'electra's father' is the definition.
I can't judge whether this defines the answer.

'turkish officer priam's nephew' is the wordplay.
'turkish officer' becomes 'aga' (military commander eg in the Ottoman Empire).
'priam's nephew' becomes 'memnon' (I can't explain this - if you can you should give a lot more credence to this answer).
'aga'+'memnon'='AGAMEMNON'

'and' acts as a link.

Can you help me to learn more?
