As mentioned as the husband of Dorthe Christfersdatter in this discussion [https://forum.arkivverket.no/topic/222506-barn-or-krone-in-digital-ministerial-record-book-for-larvik/ Knud Hansen Møller and his family brings up another challenge for me. According to two Norwegian history and genealogy experts, the use of Møller in the family names for multiple generations of Knud Hansen Møller and Hans Knutsson Møller indicates the following options: 1. This is a German family name passed down through generations. 2. This name is an honorific or title as they were all blacksmiths, referred to as Millers working in the ironworks mills. Issue One: If this is a German family name and the earliest date of record for this family is before about 1680, where would we look for some form of confirmation, migration, immigration, something to substantiate this conclusion? Issue Two: If this is an honorific/job title, and each one reached proficiency to be rewarded with this title: 1. Is this a true tradition? If so, why do I not see more Møllers in the records? I found a few, including ancestors, but only a very few in the area. If this was a special job and title, then only a few with that title makes sense. 2. Could such a title be passed down automatically (inherited) in the names of the children or is this earned? 3. Would there be certification papers, tests, or some other record form for earning the qualification? Hørte was a company town, and I understand that they have the archives in a private holding, and I may have access to a couple people who can visit them if I cannot find information outside of those records, so any help in narrowing down these two assumptions and helping me identify records to substantiate this would be appreciated. Thank you!
