the BRF and the UK in general is more title heavy than Norway, I imagine if a high ranking Royal man married a single mom of a young boy he might be granted a title (Earl most likely) at some point

No he wouldn’t. The royal family is about blood. Perhaps when he married they could grant him a title, maybe, but he wouldn’t be given anything. That’s just not how it works. The royal family have a lot of titles because they have a lot of people but they’re actually very strict about who can get what. 

Norway doesn’t have titles anymore beyond the immediate royal family. Nobility titles were done away with through legislation in the 19th century.
