At bottom of stairs turn left take hall to the end, small room on right. Look in the two filing cabinents for surname on index cards. The cards reference Liber and page. 1 The petition to apply for citizenship and 2. The actual citizenship award papers.
Early papers have little useful info but later ones list ship and towns.
Still nice to have a copy. This same room contains WWII discharge papers. The indexes to these books are located in a small room on first floor. Copy liber and page. Return to basement and retrieve book.
