 Thousands of Dutch locations in family trees are spuriously identified as "Holland, Reusel-de Mierden, Noord-Brabant, Netherlands" despite having no connection to this small village.This is due to an error in popular genealogy software Family Tree Maker, which previously would match "Holland" to a narrow, 1.3 km road named "Het Holland" (The Woodland) located in Reusel, and automatically suggest this substitution.Long after the software error was corrected, these spurious locations have persisted in trees and have been uncritically copied.
