Source:Tennessee, United States. Wills and Probate Records, 1779-2008

From Ancestry's description:

This collection includes images of probate records from the state of Tennessee. This collection includes images of probate records for approximately 96 percent of Tennessee counties. The records come from a collection of microfilm that took years to compile. They have been brought together from multiple courthouses over time to give you a single source to search. Some localities and time periods may not be included because they were not available to be acquired as part of this collection, or the records may have been lost or destroyed before the effort to collect them all began.
