Place: North Friesland - North Frisian Islands

The Burchardi Flood in October of 1634 killed more than 60,000 people in North Friesland, and swept others off their farms looking for new opportunities. Some families decided to start over in New Netherland, with several waves of immigrants to New Amsterdam and Rensselaerswyck arriving in the Dutch Colonial Period.
