"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.
