Editing/correcting "Places" in macOS Photos
Solution 1:
You can select all the photos that should be located at your home at once, and edit them together.
Open the info pane (command I) after selecting them. Type in a new location in the search box and every photo will get that new location.
If you want to find photos that are near your home, use the places view to pull up the photos you're looking for. By zooming out you'll see these photos grouped together. Then, select all of them (command A) and follow the above procedure.
