Well just to be pernickety (it's the mood I'm in!), Find a Grave only shows us the churchyard memorials for Robert and Margaret. There's no conclusive proof that they were buried there.
Nothing wrong with being pernickety , Carol.
It took a bit of digging, there are a lot of newspaper references to Robert's death, but this one states the funeral took place at the church, no mention of the vault on the estate.
I'll see if I can find any reference to Margaret's funeral, or service.
