FamilySearch has updated their listing of cancelled homestead claim files for Nebraska and Kansas. Land offices included currently are:
- Dodge City, Kansas
- Topeka, Kansas
- Alliance, Nebraska
- Lincoln, Nebraska
- O’Neill, Nebraska
- Broken Bow, Nebraska
- North Platte, Nebraska
- Valentine, Nebraska
These claims appear to have been later ones–but check the specific land office to determine which claims have been digitized.
There is more information on using these claims and finding them in my Rootdig post.
