Mississippi Index of Wills, 1800-1900 - Betty Couch Wiltshire. A master index to over 10,000 testators from 1800 to 1900. Entries give the name of the testator, year the will was probated, the county where recorded, and a citation to the source. Most wills were recorded in will books, but some were found in inventory books, marriage books, and other unusual places; some were for out of state testators with Mississippi heirs.
