I am looking for information about the ancestry of my great grandmother, Elizabeth Weider (name also listed as Wieder or Wyder). She was born in Switzerland, probably in the vicinity of Zurich or Winterthur in either 1865 or 1866. Elizabeth was an only child and was orphaned at an early age. She immigrated to the United States around 1884, settled in Philadelphia and married Anton Meindl. Any leads on Elizabeth or on Weider families residing in the Zurich/Winterthur area in the mid-1800s would be appreciated.
