Is this any more complicated than -drop if missing(sid)-?

Dear stata maestros,

I have a following data set

nh pid  sid  age  educ
1    1    2   34    3
1    2    1   29    2
1    3    .   21    2
1    4    .   27    1
2    1    3   44    12
2    2    .   23    9
2    3    1   31    11
2    4    .   19     2
2    5    .   27     3
.
.
.

nh is the household identification no and pid is individual identification within each household. Sid is the spouse identification no for those people who are married within a household. So for nh=1, it means pid 1 and 2 are married to each other and for nh=2, pid 1 and 3 are married to each other.

What I want to do is to make a datasets consisting of household members married to each other. That is, in the new data set I want to keep , for nh=1, pid 1 and 2 and for nh=2, pid 1 and 3. So what I am trying to find that for each nh, take those pid for which sid equals pid from others observations.

Is there anyway to do it rather than going through each observation individually?

Any help would be highly appreciated.

Thanks

AmBush
