Nah, I can’t think of any reason tbh. Just somehow unexpected I guess because I usually only hear it in the name of the german state Mecklenburg-Vorpommern.

I mean, I know that many if not most places in the US are named after European ones, but somehow Mecklenburg caught me really off guard just now

That reminds me of a video by Angela Collier about that and similar phenomena https://youtu.be/wBBnfu8N_J0
