I sent for a will/probate from the GRO index all the information was right exept there wasnt a folio number I had a repy stating this ,I have checked again but there isnt one unless its somewhere I havent looked the search is for 1992 I cannot put anymore information as there are still living family any elp ould e appreciated
There is a similar historical query on this , Google folio number will.
The advice then was to send an email with all the details you have and stating the folio number is not given. The experience was that it worked.
