In the Netherlands, every region, sometimes every town, has its own particular dialect. If you want to hear how the people in your ancestors’ region sounded, you can listen to audio clips at the Meertens Institute website.
- Click on the + before the province
- Click on the name of the town, which will open a pop-up with a list of recordings.
- Click on “Afspelen” [play]
Most of the clips are anonymous.
You can also click Kaart [map] to see the recordings on a map or click the Opnames buiten Europa to hear recordings of Dutch people living in other countries, such as the Verenigde Staten [United States].
I noticed one of the places named in the USA is Edgerton, South Dakota. I can only find a Edgerton Township in Hanson County, South Dakota but no city or population center near there. There is an Edgerton in southwestern Minnesota which is a fair sized city with a large Dutch population. I’m thinking South Dakota may be an error and should be MInnesota instead.
That sounds like a plausible explanation.
