There seems to be some incorrect info about naturalizations. The ones from the 1850's thru 1905 are still in the Lackawanna Co. Courthouse in the Clerk of Judicial Records on first floor. What was moved to the new part of the Federal Courthouse is the index on microfilm from 1906 on. There is a lot of infomration on the cards, but the files themselves are in the National Archives in Philadelphia. Tom
