The use of a farm name is indicated in records as the family surname linked to the farm name with the term "genannt," meaning "called." Genannt is usually abbreviated as gt. or gen.
The name "Burlager" seems to have been used to indicate he came from a farm at Burlage, or lived on a "Burlager" owned farm. He also used the names "Olliges" and "Hanneken," indicating that he worked at or owned farms associated with those surnames.
Alias surnames were often tied to agriculture. When a man moved to a new farm, he sometimes changed his name to the name of the farm. Also, when a man married a woman who had inherited a farm, his name may have changed to her family name.
