Understanding Society User Support

Good Morning,

I am working with the first 5 waves of the UsoC.
I am currently trying to undertake a within household analysis for siblings.

I am struggling to find a variable that allows me to identify the person roles within the household, that is who is a father, mother, sibling?, etc.

Is there any variable in the first 5 waves that does this?

That is, ideally, there would be a variable that does the following:

In HH1:
                                If respondent is father = 1
                                              is mother = 2
                                              is son = 3
                                              ...

etc.

Hope that makes sense
Thanks.
