Det er harmløst og interessant og finne ut hvor røttene man har kommer fra. Hvis du ønsker å finne ut mer kan du bruke "Digitalarkivet". Gamle kirkebøker og slikt er søkbare, så hvis du vet navnet på personen som flyttet til USA fra Norge kan du søke opp han/hun der.

Norst høres ganske trøndersk ut?

There was also a dialect of German spoken in Texas by the descendants of German immigrants. It had some divergences from anything spoken in Europe. It’s probably extinct by now, as the speakers largely switched to English around the time the US entered WW2. A decade or two ago, a university in Germany sent some linguists to interview the remaining speakers, the youngest of whom were in their 60s.

I can see that there are hints of northern Norwegian, like Æ and MÆ as personal pronouns - reminds me of my chatty aunties in Seattle, the family was originally from Svolvær in Lofoten.

There are some Norwegian speakers in the States that can speak quite pure Norwegian, but from what I've read, it seems to be a form of Norwegian that was common close to a hundred years ago.

Fun fact; there are about as many Norwegians in north America as there are Norwegians in Norway.
