American at home with English princess by noon (8)

I believe the answer is:

indianan

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

'american' is the definition.
(I know that Indianan is a type of american)

'home with english princess by noon' is the wordplay.
'home' becomes 'in' (to be in is to be (at) home).
'with' says to put letters next to each other.
'english princess' becomes 'diana' (I have seen 'British princess' mean 'diana' so perhaps 'princess' could also mean 'diana'. I am not sure about the 'english' bit.).
'by' means one lot of letters go next to another.
'noon' becomes 'n' (abbreviation).
'in'+'diana'+'n'='INDIANAN'

'at' acts as a link.

Can you help me to learn more?

(Other definitions for indianan that I've seen before include "American statesman" , "Mid-Westerner" , "Local American" .)

I've seen this clue in The Times.
