▶︎ The Basics of Researching in Cass County
The Basics of Researching in Cass County
  • There are no known courthouse fires or massive record destruction
  • After a period of time, a majority of county records are sent to the Historical Society
    • However, that cut-off year varies based on record type
  • Some county departments have online document search databases featuring select record collections
    • Some allow copy requests by email
    • Others will require a visit in person to get copies of records
Finding Your Ancestors in Records and Indexes
  • Consider the terminology the record uses
  • Your ancestor might be listed in indexes as:
    • Juror, witness, victim, defendant, plaintiff (criminal/civil court records)
    • Grantor, grantee, executor, administrator (property/land records)
    • Deceased, informant, registrar, undertaker, physician (death registers/certificates)
Reading Historical Documents
  • Earlier records are often handwritten
  • Typed records start to become more common circa the 1940s
  • Keep this in mind when using transcriptions and indexes
    • Illegibility of the handwriting may account for spelling variations or inaccurate information
    • Information in indexes is at least three degrees removed from your ancestor:
      1. The clerk hearing and recording the information in the record
      2. The transcriber reading the handwritten information
      3. The transcriber recording the information in the index
    • This can alter the information over time, like a game of telephone
    • Errors can happen at any step — i.e. a careless or inexperienced transcriber misreading a name or maybe even an ancestor lying about their age
Reconnaissance is Key
  • If you are unsure where a particular record type for a given time frame is kept (i.e. a deed in the 1940s), call ahead to the county office responsible
    • If you do not know where to find a record, contact the Genealogy Branch to be directed to the right place
    • This will avoid wasting time looking in the wrong place
  • Check the Cass County Historical Society first for historical records in their archives
    • i.e. records dated prior to the early–mid 1900s
    • An index of records held at the Historical Society may be available at the Genealogy Branch – check our Indexes
