Wish I could help more... I looked in my "South Dakota Geographic Names" book...circa 1973
... It lists almost every South Dakota geographic place that is or was...
Here is the section on Orland:
ORLAND (Lake Co.), 12 miles southwest of Madison, was called Orlando in the early days but the reason for the name is not definitely known. When a consolidated school was built in the neighborhood, the store was moved nearer the school and other establishments, including a garage, filling station, blacksmith shop and refreshment parlor, were soon added.
Here is the StreetView link via Google Maps:

If you're not familiar with StreetView, click anywhere and hold your mouse and move it.... You can do a 360 of the area. If you want to move up and down the road, click on the arrows shown.
