What Can I Learn from Naturalization & Probate Records?

  • Name of the testator or deceased
  • Names of heirs, such as spouse, children, other relatives, or friends
  • Name of the executor, administrator, or guardian
  • Names of witnesses
  • Dates the documents were written and recorded (used to approximate event dates, since a will was usually written near the time of death)
  • Court where will is filed
  • Date of filing
  • Conditions of the will
  • Land descriptions

  • Residences (including previous residences)
  • Date of immigration

How Can These Records Help Me Find Other Records?


With information from these records you may be able to:

  • Use the residence and names of the parents to locate church, land, and census records
  • Use ages to determine approximate birth dates
  • Use will filing or probating dates as approximate death dates
  • Search for records of people in the county who shared a surname. These may have been the couple’s parents, uncles, or other relatives. Your ancestor may have been an heir who sold inherited land that had belonged to parents or grandparents
  • To find later generations, search the land records a few years before and after a person’s death. Your ancestor may have sold or given land to his or her heirs before death, or the heirs may have sold the land after the individual died. For daughters, the names of their husbands are often provided. For sons, the given names of their wives may be included. Heirs may have sold their interest in the land to another heir even though the record may not indicate this. Continue this process for identifying each succeeding generation
  • When looking for a person who had a common name, look at all the entries for the name before deciding which is correct
  • Some counties were subdivided or the boundaries may have changed. Consider searching neighboring counties as well since that courthouse may have been more convenient for the person
  • Witnesses and neighbors, even those with a different surname, may have been relatives, in-laws, or even a widowed mother who has remarried. You may want to check the records of these witnesses and neighbors, especially if they are frequently found in your ancestor’s land records
