I can't quite make it out but the black and white half of the arms of John Affleck of Dalham Hall. The impaled arms must be those of his wife Neeltje (née Schape, of Amsterdam) 1663-1729. They were the parents of Gilbert Affleck, MP and grandparents of the first two Affleck Baronets of Dalham Hall.
Does anybody recognise the impaled arms. Either what they would actually be, or who they would belong to? I'm guessing they would be Dutch Burgher Arms of Neeltje's father Gilbert a merchant.
