The next two letters refer to the probate office that handled the will. This will be PO for the main probate office in Dublin. A list of the two-letter codes for other district probate offices is on the probate office register site – for instance MR for Mullingar or LD for Letterkenny. You’ll need the whole record number to apply for a copy of the will from the relevant probate office.
