Only few German names are as common as the name Hoffmann- no 10 of most popular German names (followed by M?ller, Schmidt, Schneider, Fischer, Weber, Meyer, Wagner, Becker, Schulz: all profession-denotations).
We are the German-Baltic Hoffmann family, whose ancestors used to live in the Baltic States (i.e. Estonia and Latvia). If your name is Hoffmann and your ancestors came from these Baltic States then you are a relative.
But: ?The "Estonian Hoffmanns" with their side branches do not build an entity of it's own (as formerly presumed): they are only a part, a branch from a widespread German family, who are descending from the blacksmith Philipp Hoffmann (ca.1540-1610) from Sangerhausen in Thuringia.?
