re: Who's kids belong to who? Home Alone

quote:

I remember that somewhere it was mentioned that Heather is Uncle Rob's daughter

You are correct!!

Joe Pesci: Excuse me miss, are you parent's home?
Heather: My parents live in Paris, sorry

By that logic, that would make Sondra Uncle Rob's daughter too

Joe Pesci: Are your parent's home?
Sondra: Yeah
Joe Pesci: Do they live here?
Sondra: No

If her parent's were home, then they are not Uncle Frank and Aunt Leslie because they are at Peter's house

Corrected
