[Facts] Re: Nordic Name help
A verbatim search of "Styburg" produced a grand total of 219 results on the entire internet, but that number fell very quickly once I weeded out the typos and scannos.
However, there is the Old Norse name 'Stígr' which is the agent noun of 'stíga' ("step, tread, set foot on"; 'stígr' itself meaning "path"). Most modern Nordic languages have this as 'Stig' (Icelandic 'Stígur'). As for the "-burg" element, the Old Norse word which I think fits most thematically would be 'byrr' meaning "favourable wind".
According to Old Norse morphology, the compound name of this would be 'Stígbyrr', however this is unused. If you are going for any sort of fiction that does not rely too heavily on accuracy you could use this or a spelling variant (note that Old Norse 'g' before another consonant is commonly dropped in modern descendants). But if you want a very historically/linguistically accurate story, I recommend using 'Stígr' or one of its modern descendants, and/or consulting people from or experts in that culture.
