Buddha girl, you are from the north-east. There is a Polish church and Polish club in Newcastle-upon-Tyne. There has been a Polish club in the area for at least thirty years that I know of. It might be worth a try asking some of the older folk at the club. Of course there might be more than one club, but it's still worth a try.
Most Polish who settled in the north-east, around WWII and before, were Jewish. If this applies to you then check Jewish records for the area.
