Pastor Siegfried Kastler (a Swabian Kastler) from Heuchlingen, Germany made an interesting discovery while researching his ancestry. He found an inscription in an old “Lagerbuch” (contains information on farms, taxes, etc.) from circa 1540 of the Abby of Söflingen. It pertains to a village called Burlafingen near the town of Ulm. The inscription reads: “Ulrich Mayer, genannt Castler” or “Ulrich Mayer, called Castler”. Siegfried states: “This means the former name was Mayer and Castler was a profession, which changed later to a surname”. It is an accounting of property given by the church to Ulrich via tenure. As of the writing of this document in 1540, the Swabian Kastlers were well established as a family, with the name spelled “Kastler” since the early church books and tax records.
The meaning of this name is not known. It is perhaps the theory of Castler which has to do with money. You can read the Surname Origins to get an idea of different options.
