Is the following question grammatically correct?
"Where are Sue and your daughter?"
Context: Sue is the wife, and the mother of the daughter.
If Sue is the mother of the daughter in question, why wouldn't you ask "Where are Sue and her daughter?" The only way "your daughter" would work would be if the question were being addressed to the father of the daughter.
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
