On 18 October 1906, during the terms of Governor Joaquin Luna and Mayor Primitivo Resurrección Novicio, the town was renamed "Luna" through "Philippine Commission Act No. 1543". It was the first town that altered its name since the creation of the province in 1850. The change was to honor the famous Luna brothers: Revolutionary General Antonio and "Spoliarium" painter Juan; their mother, Doña Laureana Novicio Luna, was a native of Namacpacan.
