A few years back, Plessa (Amygdalia) had a website. Someone went through the United States Ellis Island records and pulled the names of 200+ villagers who came to America for work. The website is gone, but I still have the spreadsheet and have uploaded a copy here. Amygdalia-Plessa Variations Immigration
In the intervening years, I’ve created my own spreadsheet and added much more content- the names of the ships, who they were traveling to, who they left behind. This is not completed, but I have also uploaded the most current copy. I will update it as it changes.
