I have traced my Schnieder's back to 1702 and they all seem to come from or die in Alfhausen, Hannover, Prussia. The last being named: Johann Gerhard Schnieder. Our name is spelled "ie" rather than "ei" which makes it difficult for me to find information.
All was Researched: Katholische Kirche Alfhausen, Hannover, Kirchenbuch, 1679-1875; Tote, page 283 [Church book, 1679-1875: Deaths], Fiche Book 05-10-002, Book 3 [Microfiche of original manuscripts located at the Bistumsarchiv Osnabruck in Osnabruck]. Document 17.
