Records, what they contain and how they are created and recorded can change over time. Their organizational structure can change as well. Learn what is different about the records. In one time period there may simply be one ledger or record book for the probate records. At other times there may be a separate set of records for probates and for guardianships and those records may consist of separate ledgers and original packets of records. It could be that later the probates and guardianships are kept in the same set of materials.
