Juraschka Ancestry

Interested in learing about Juraschka ancestors from Wewirschen/Wewerzene/Wewirziany Lithuania.  I was told my great-grandfather Michael was one of 16.  He came to the USA around 1912.  His brother is Bernard Juraschka of West Germany.  He had a sister Marie.  If anyone has any knowledge of this family I would love to learn more.  Thank you!  Jeannie
