The name Hirschland was adopted by three brothers in Steinheim, Germany, after the local government required that Jews in the area adopt family names. Previously, the practice was to use one's father's first name as one's last name. This could create problems, such as when Herz Saloman father Salomon Herz, who later adopted the name Hirschland.
The original Hirschlands also all had a connection to Essen, Germany, where Salomon Herz Hirschland, and all his children, moved after his wife died. From Essen, the HIrschlands have spread around the world, with major nexues in the United States and the United Kingdom. For more information about this family, check www.hirschland.com.
