This being Norway in the early 1800's, I didn't think they had last names yet, but Sahlqvist and Wright do look like they are being used as last names. Seems too early for that, but then, the aristocracy and tradespeople were the first to use fixed last names. I'd be interested in hearing what Sahlqvist means. Wright may be a craftsman, like a wheel wright or similar, but it would be better for someone who speaks Norwegian to say for sure. But since they appear to have lived in the village or city, they may have been tradespeople with some of the first last name usage. Kirsten should probably still be just Kirsten Wright, not Sahlqvist. For most people of the time, names changed every generation Wives didn't take a husband's name, although she might be associated with a new farm (or village?) name.
