I could swear I posted this question already but I can’t find it. 
In the episode of the Simpsons where prohibition is introduced the town clerk appears having found out that prohibition had been repealed many years before. What sort of accent does this character have? Is it just meant to be a generic “old-timey” accent or is it a regional accent in the US?
From memory, its a “New England Accent”, the accent used in the more remote bits of VT, NH and Maine, usually by older folks.
If I’m remembering correctly, it strongly resembled a thick New England–probably Maine–accent. Most of my family was originally from Maine, and the locals talk like that.
Here you go. Couldn’t find a clip of the Simpsons character though.

Maybe it was in Cafe Society?

Another vote for New England. The town clerk voice was later used as the voice of a very old prison guard, and even later, as one half of the couple George and Martha. (George sounds like that old town clerk, and Martha sounds like Katherine Hepburn.) Over the last few seasons they’ve appeared as an RV-driving couple and as a pair of New Hampshire voters who stick up a restaurant, among other places.
