Klein Jannewitz

Hello List,
  I am searching for information on the BRIESCHKE family from Klein or Gross Jannewitz, Kreis Lauenburg. My ggrandfather Wilhem Brieschke was born there on 1 Dec. 1851. He married Caroline Panzer before coming to U.S. abt. 1878. Any info about this family would be greatly appreciated. Thank you.
