I found a link through a heraldry site to a 900 page book containing many ancient family coats of arms. On the 40th page I found the de Büren family crest. Unlike lions, symbols, or geometric shapes which are plentiful in heraldry, bee hives are unique. The name above says "Burron" which is how the name of the town Büren, for which we are named was once written. As I perused many of the additional pages I recognized other Swiss families of note from the period, among them Erlach, Hofmeister, and Neuchâtel.
The author and painter Vigil Raber created in the 16th century a collection of 7244 coats of arms of families primarily (I believe) from within the Holy Roman Empire. The book is housed in the Duchess Anna Amalia Library in Weimar, Germany, a public research library for literary and cultural history with a collection focusing on German literature from the period around 1800. It also preserves literary documents dating from the 9th to the 21st centuries as sources of cultural history and research, indexes them according to form and content and makes them available for use. The library collection amounts to 1 million articles.
