what's-their-name's daughter

So I am on the phone with a woman I do not know who is making me a job offer for next fall. My children's origins come into play and she tries and tries to bring to mind the name of an other local family that she knows that have adopted from Russia. She can't find the name so the conversation moves on and eventually comes to an end.

A few minutes after we hang up the phone rings again. It is the same woman. She has remembered. It is the daughter of her husband's friends. She then names my parents. Why yes! I do know that family ~ quite well in fact.
