IIRC, the majority of the Little House series was based in Walnut Grove, Minnesota, not Kansas. Walnut Grove has a Laura Ingalls Wilder museum and they host a large festival each year based on her books.
Laura, Almonzo and some other family members lived very near where I live right now in the Florida Panhandle. There is a historical marker there and also a little park.
One of their descendants still lives next to the old place.
My Great Grandfather performed the wedding for two of the family. He was a Baptist minister.
Warning - offtrack subject!! The Little House on the Praire show is set in the town of Walnut Grove, MN. Their original sod house was there on the banks of the creek. IIRC it is just a depression in the ground now. BEAUTIFUL area and a great place to see. Park in someone’s driveway for a small fee and walk past the newer farmhouse and down aways to the creek. And the museum is in town.
A place I would REALLY recommend is where their farmhouse, depicted in the show, really was - near De Smet in South Dakota.

Some farm family loved the Little House on the Prairie story. They ended up selling their farm in Nebraska(?) and bought the original Wilder property several years ago. They built a recreation of the house based on her books, a barn, etc. They moved a local one-room school house from the nearby town out to the far side of the property. You take a horse-drawn wagon to get out there. Guides are in period-costumes, crafts for the kids (rope making, candles, milking, etc.) Costs $10 per person!!
Lots of fun for the kids. We did it several years ago on the way to Minneapolis. (The place in SoDak and MN), then saw the play “Little House on the Prairie” in Mpls. where the young girl actress from the show played the mom in the play. My girls LOVED it!
