If the OP has mentioned all the beneficiaries, someone presumably receives any unmentioned 'leftovers' - who will normally be any surviving widow. She will remain in the house now owned by that son. Maybe the other sons (except the one with the shilling) are now independent and don't need support?
My Devonshire yeoman ancestor died in 1851 aged 82, leaving over £230 (and his Clock) to various descendants - a tidy sum in those days. Everything else, after testamentary expenses, went to a son who was his executor, who received no specific money. There was no widow, and no buildings or land to pass on. Within a few years that son had decided to try his luck in Ireland.
