Hello. Thank you for your message but unfortunately it appears they are two different people. My mother used to say his Greek name was Petrugus or Petreugis and as you mentioned, there are many different ways to spell names in those days. I have confirmed some of his records after he married my grandmother, but prior to this - nothing. (I realise I should change my message board to show these names rather than Peters.)
It was lovely to hear from you something of a bonus this family research brings - meeting people with the same interests.
All the best in your research.
Regards
Carolyn
