The United States Assistancy
Although Jesuits appear, just briefly, in Virginia and Florida in the late 16th and 17th centuries, the United States Assistancy (until recently called the American Assistancy), begins in 1634 with the arrival of Fr. Andrew White on St. Clement's Island in the Potomac River, off the shores of Maryland. The Assistancy today is made up of 10 Provinces comprising the 50 States.
The Jesuits of the United states maintain 70 secondary and primary schools serving 51,346 students staffed by 487 Jesuits, 7 technical institutions served by 4 Jesuits which served 3,131 students, 31 Universities and colleges with a total enrollment of 187,077 students served by 876 Jesuits, and 1 seminary serving 19 students in which 1 Jesuit works. There are 17 social apostolates operated by 39 Jesuits, 138 churches staffed by 307 Jesuits, 31 retreat houses served by 120 Jesuits and 7 spiritual centers served by 21 Jesuits.

Thanks. That takes care of 10 of the leaders. I'm not sure who the 11th would be. Perhaps a Superior General for the US?
