I did put Beurle in Google and it appeared to be German, however, talking with a very old relative who has just got in touch with me, she reckons that the family came across the channel and were dumped by their father, Pedro, who disappeared. She says the family are definitely from the continent and she reckons there is some sort of Spanish connection, especially as there was another relative, Fidell, anyway, I am sort of getting round to the notion that they have come in off the boat somewhere along the line and that the Chatham thing might be a red herring....there seems to be some evidence further down the line that they might have been a little economical with the truth when it came to official records.....
But I'll keep looking, they must be somewhere!!!!!
Thanks loads for your help!
