Chris,
The family story is that John? stowed away on a ship at Genoa and arrived in Scotland at the age of 14. he is on the 1851 census at Biggar aged 15.
If he arrived at a Scottish port I wonder if he could slip into the country and just tell people that he is a British subject as many do today.
We believe he went to Biggar as there was already Italians living there, they were not on the 1851 Biggar Census. I am trying to find where they came from.
On the NA naturalisation list there is only one name that looks like John Lando, he is John Albini but he registered in 1845. I will get a copy to check if not I will go to the NA.
