Familysearch.org has an Index to Wise Co Probate Records that begins with 1882. You can read it at this link: https://familysearch.org/pal:/MM9.3.1/TH-1951-30684-17520-81...
You have to have an account with FamilySearch.org, but it is free. I have done research on Wise County for about 30 years and I have never seen a published book of Wills or Probates. I have been to the Wise Co Courthouse and was disappointed in the available records prior to the 1880's. I have read there was a courthouse fire in 1895.
Newspapers.com has the Wise County Messenger, 1883-1980. I have found many obituaries and stories regarding family members by reading this newspaper.
