The place of citizenship for the Bonadurer family remains Versam<\/strong>, Graub\u00fcnden. Although Versam merged with Safien, Tenna, and Valendas to form the political municipality of Safiental<\/em>, the place of citizenship, Versam, remains unaffected \u2014 it continues to exist as an independent citizens’ commune. <\/p>

While many Bonadurers emigrated all over the world in the 19th and early 20th centuries \u2014 to America, Russia, Brazil, and Poland \u2014 part of the family remained in Switzerland, returned, or resettled in other Swiss cantons. <\/p>

Place of Citizenship Versam \u00b7 Safiental<\/h2>

Versam \u2014 today part of the political municipality of Safiental \u2014 remains an independent citizens’ commune. For all Bonadurers whose ancestors come from Versam, Versam is still the official place of citizenship. This also applies to those lines that moved to Zillis, Chur, or other cantons in the 19th century. <\/p>

The oldest parish register entries of the Evangelical Reformed Church of Versam (1705\u20131875, filmed by The Genealogical Society of Utah, 1980, State Archives Chur) are the cornerstone of all Bonadurer family research. Without them, the connections to the American, Russian, and Brazilian branches could not be proven. <\/p>

The Bandur farm (Wiesenheim \/ Wieshus) is located in the municipality of Versam and is still part of the extended family network today. Anyone who has current information about the present residents is requested to contact Roland. <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t
