Muckerman

Hello,
  I am looking for information about 3 brothers, Johann, Everhard, and Christophe Muckermann who left their home, a farm near Clarholtz in the 1840s or 1850s to emmigrate to St. Louis, Missouri US.
   
  Does anyone know if people from this area were involved in the Peasant Revolt of 1848? I am wondering if this could be the reason the 2 oldest sons would have left the farm?
   
  Also looking for information on the Biekart or Bickert or Ortmann families who were probably from Westphalia as well.
