Descendant of Homer is found in LA (4)

I believe the answer is:

lisa

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

'descendant of homer' is the definition.
The definition suggests a singular noun which matches the answer.

'is found in la' is the wordplay.
'found in' indicates putting letters inside.
'is' going into 'la' is 'LISA'.

Can you help me to learn more?

(Other definitions for lisa that I've seen before include "Most intelligent of Marge Simpson's children" , "Mona ..., also called La Gioconda" , "Girl" , "Mona . . . ., famous painting by Leonardo da Vinci" , "Leonardo da Vinci painted the 'Mona ....'" .)

I've seen this clue in The Times.
