I don’t mean to be negative, but visiting any major tourist attraction or station or other possible terrorist target in New York these days entails being searched and eyed up and down by men with machine guns and K9 units, and security guards, and being yelled at by uniformed officials.Interestingly, a lot of people's ancestors who supposedly came through Ellis Island didn't. It became something of a generic term. Folks didn't know exactly where they came through, and attached the most recognisable name to it afterward.
The only good part about it when you are going to Ellis Island is that you will start to empathize with how the immigrants felt: being told where to go, and being afraid of uniformed authorities bossing them around who can prevent them going where they want to.
I have the seaman's book for my great-grandfather, Frederick Lindquist, who went to sea around 1849, sailed the world, and came to America to stay in 1867. I have no idea what port he entered through, but he settled in Rhode Island, where there were a lot of Swedes who had been recruited to work in the velvet mills.
