My DH's grandmother died earlier this year. His parents told him he would be getting some money, they couldn't initially say how much. Knowing that we were in the midst of a spiralling building project they offered to give us the money before the funds came through. It was a really welcome offer. They have transferred 12,000 big ones into our bank account in two installments. Frankly it made a massive difference.
Here's my issue: I Don' t know whether the money was left to DH by his grandmother or whether his parents shared their inheritance. I asked DH and if he was told he's since forgotten. I feel like it's important for us to know to whom we should address our thanks for this kindness. DH is vaguely reluctant to ask. He would if I pressed the issue, but I don't think he sees anything unresolved here. There's nothing big at stake, we have a super relationship with DHs parents and they have shown huge kindness and generosity to us always. Equally we (mostly DH obvs) have very fond memories of his grandmother.
Is this point about the inheritance relevant or irrelevant?
