I do not see any problems Ed.

You have link PersonePhone.
You can do 2 task:

1) you know some person recID and you want find its Phones:

        linkPersonPhone.FindLinked( recid, tblPerson, tblPhone );

2) you know some phone and you want find persons that use it

        linkPersonPhone.FindLinked( recid, tblPhone, tblPerson );

Easy and clean !!!

Where you see problems ?
