Jablon, Lutenberg, Litzburg

My maternal great grandparents left Prussia (Litzburg, Lutenberg, Jablon) in about 1887. Their immigration papers listed Poland/Grtmany as their birth countries. I believe that they both came from Catholic families. Both could read and write, but neither spoke English at the time of their immigration to the U.S. I suspect that they both spoke German and Polish.

My maternal great gradfather's name was Theodore Danielewski/Daniels and his father was Frank Daniels.

My maternal great grandmother's  maiden name was Hellena Miller and her mother was a Zgozelski or Goczwelski.

Please tell me whatever you may know of the probable happenings in or around Litzburg, Jablon, and Lutenberg between about 1850 and 1900. Of course I will be very pleased to hear anything which you may tell me related to these great grandparents of mine.

I believe that they left Prussia just about at the same time the railroads were being nationalized.
