Hi, Aleš-
Sorry about the confusion- I was still getting used to the WikiTree+ site, & wasn't certain how best to phrase my answer. Having seen the 911-913 suggestions, I agree that they're a good place to start. Norwegian patronyms are a little more inconsistent than Swedish ones in spelling, however, which hopefully the suggestions can compensate for; the rules, as I believe would be most befitting, follow:
Norwegian equivalent of 911: Norwegian patronym -datter/-dotter for male
912: Norwegian patronym -sen/-son for female
I'm unaware of the internal mechanics of the 913 suggestion- are the 911-913 suggestions programmed specifically for Swedish profiles? Just for the sake of experimentation, I tried searching 913 for profiles with Norge in them, to no avail, so I'm assuming that's the case. A similar, or even identical suggestion for Norwegian profiles as "Norwegian patronym -datter abbreviated" would work.
Beyond the existing suggestions for Swedish profiles, I was thinking primarily about conventions with relation to WikiTree naming fields. Again, I'm unaware of much of the internal mechanics required, so I'll try to explain as best I can, & you can let me know if it doesn't make sense, or anything else.
1. Norwegian gårdsnavn (or farm name) used instead of patronym.
This would apply to profiles born in Norway before 1860 (&, in some areas, up to 1923, but 1860 seems like a reasonable cutting-off point overall), where the LNAB does not end in -sen/-son or -datter/-dotter. It's designed to take into account the requested & accurate naming customs of the time period, & helps prevent disorganization & confusion among Norwegian profiles on WikiTree.
& the other suggestion I'd like to see & be able to use is essentially the same as 749:
2. Middle name used in Norway (prior to 1923).
With rare exceptions, a middle name, as we recognize it, did not exist for Norwegians prior to the full adoption of surnames, & most Norwegians who were given multiple names prior to that time used them in tandem. This is elaborated upon in the link I put in my original answer.
I think that's most of what I had in mind. Please let me know if I can elaborate on anything, or if I can do anything else
