LNAB for some profiles is the English version, for some the local version, for some the "house" for some, the inherited name, some for the region, some for the country. I see duplications everywhere due to different LNAB's. I'd like to find a consensus on which names to use for different eras. For example, if the person is a member of a "House," should that be the standard for that era? In Scandinavia, last names change with every generation, and I've seen "Norge," Danmark," etc. as an LNAB. I know this has been discussed a lot, but I still see variations every day. Doing a search of "Denmark," I am not going to find "Of_Denmark," and "avDanmark" or "Oldenburg," or "Oldenberg" unless I have enough experience to do this kind of search for myself.
We could eliminate a lot of misdirections if we could settle on a guideline by regions and by dates. What I mean by that is a chart or something listing by 1. "country, (Sachen, Saxony) " 2. by date (from "1100-1450,") the royal LNAB should be "____."
If such a directory exists, I have not found it.
