I would like to thank all those kind people who replied to my posting.
However, my question was not about whether or not immigration officials at
Ellis Island or any other US port changed names of immigrants.
What I wish to know is: is anyone aware of the existence of authoritative
evidence regarding the question of name changes by immigration officials at
ports in countries other than the US, and particularly Canada and Great
Britain. US rules and procedures simply did not apply.
Evidence in this context means either first hand evidence (not family
stories) of the immigration experience or rules in force at the time. I'm
afraid that anything else is speculation.
