Somewhere in Holland, cad meets mother (9)

I believe the answer is:

rotterdam

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

'somewhere in holland' is the definition.
The definition and answer can be both locations as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'cad meets mother' is the wordplay.
'cad' becomes 'rotter' (I've seen this in another clue).
'meets' means one lot of letters go next to another.
'mother' becomes 'dam' (female parent of an animal).
'rotter'+'dam'='ROTTERDAM'

Can you help me to learn more?

(Other definitions for rotterdam that I've seen before include "Dutch city and port" , "foreign city" , "Netherlands port" , "city abroad" , "European port" .)

I've seen this clue in the Sydney Morning Herald.
