You are right that /vinaa/ takes instrumental (or ablative) but I don't think you need a pronoun there at all. Just /parisaaya/ by itself is enough. The word 'her' in the English should be left untranslated, and even if you want to include the idea, it can't be translated with /tassaa/ if it is referring to the mother in law's retinue. You would have to use /attano/ in that case.
Compare:
He raised his (own) son:
So attano sutam posi.
NOT: So tassa suta.m posi. This says that he raised someone else's (tassa) son.
This applies in all genders in the third person.
Note that: Aha.m mayha.m suta.m posi | is okay. The restriction only applies to the third person.
best regards,
