Before the 20th century, all Norwegians used to have names like Hieronymus Aschehoug, Christian Schweigaard, Edvard Grieg/Munch and Baltzar Beck, before everyone started adopting names like "Leif", "Harald", "Olav", "Vetle", "Håkon", "Einar", "Ingrid" and "Vigdis" to LARP as Vikings

Not true.

Also, the vast majority would not have had fancypants last names like that.

The majority of Norse names in modern Norway are LARP names. Your list is just bastardised names of saints besides Knut and Bjørn

>>211791964 (OP)
these names are from the era of Latinate snobbery, when Latin was the European lingua franca and language of science

1600s-1700s uni educated Danes would rename
Kjær -> Paludan
Smed/Schmidt -> Faber/Fabricius
Kolding -> Collin
Broby -> Pontoppidan
etc..

We even have 1700s comedy poking fun of the trend (Ludvid Holberg's Erasmus Montanus)

in 1600s 1700s Latin was cool. and names associated with German nobility too

in this period few cared about Vikings
