Did your ancestors come through Ellis Island?
If so, then a description of the medical process and hospital system that they likely had to endure, is presented in a new book and film by Lorie Conway titled "Forgotten Ellis Island."
Thousands of families were separated and an enormous amount of them were sent back or deported because of various medical problems.
A website regarding her book, with maps and photos is located at http://www.forgottenellisisland.com/FEI.swf
