"de Casa" added - 1916 nomenclature reform

1916

The 1916 reform of Spanish municipal nomenclature, the one that disambiguated the dozens of "Santa Bárbara" and "Villanueva" entries on the national rolls, extends this village's name to Santa Bárbara de Casa. "Casa" likely refers to the casas (homesteads) that had named the larger of the two original hamlets.
