Further to the debate on name-changing, there are a few scenarios
whereby people could have used "nom de plumes." One possibility is
that they did use forged documents or documents belonging to someone
else. Without photo ID this was probably a lot easier to accomplish.
Another possibility that springs to mind is the idea that a relative
who had already immigrated and Anglicized his name, could have sent
back tickets in the names of those he was bringing over with
Anglicized names, or he wrote a letter to his emigrating relatives
telling them to use Anglicized names (which he may have suggested)
rather than use their real East European names.

Just a thought or two.
