What is Claus short for?
In old records, Claus is usually short for Nicholas. It can also stand for Nicolaus and Klaus. You will find it in German-immigrant, Dutch-immigrant, and American records, chiefly 1700s-1900s. The Claus-to-Nicholas jump is easy to miss, so it is worth searching both when you hit a dead end.
