Hi Diane
You really need to be able to find a place of birth to make progress, especially as the name looks more Ukrainian than Polish - he could have been a Greek Catholic from what is now the SE of Poland or W Ukraine. Did Teodor become a naturalised British subject? If so, there might be some record of his place of birth in his naturalisation record. Or was he a UN-recognised Displaced Person at the end of WW2? If so, there are surviving records (not online, in Germany) which could give a place of birth and names of parents.
