These are the earliest Kastlers and Kastners currently known who have been mentioned in a document, the family trees, or church/tax records on this website. Persons who are known to have existed earlier than when the church books were starting to be used, typically the mid 1600’s, are rare. It’s unfortunate that church records do not go back further than that, although a few do go back into the late 1500’s.
