breed of cattle, 1865; so called because originally raised in nearby Friesland. The place name is literally "woodland settlers," from the roots of German Holz "wood" (see holt) and siedeln "to settle," altered by influence of Stein "stone." Since 15c. it has been united with the Duchy of Schleswig.[Holstein etymology, Holstein origin, 英语词源]
