Thanks so much for your help and advice.
So it sounds like the best thing to do is to get a specialist to check the Sora records for me...?
I have a better idea on names and birth dates etc. so perhaps that should help... I hope.
Not sure if they did go to Birmingham at all first as they were all in London for the most part.
Are you able to recommend an Italian researcher?
Hopefully it's not too expensive....

I've joined Ancestory which has been great. And opened a few questions!
But I shall also join findmypast and check the census for 1911 as technically I think they should have been in the UK by then.
I'm going both backwards, forwards and sideways with this so far! I'd love to find some connected living relatives. That would be amazing.
Thanks to you all so far for your help and tips.
Let me know the name of the researcher when you have a moment.
Cheers all.
