The county of Livingston started recording marriage records in 1836. This is a very early period of time as compared to many other counties. The records are located at the courthouse in Howell.
All of the marriage records are indexed. Be sure to pay special attention on marriage records to who the trustees that are listed. They often provide valuable clues to family relationships that are often overlooked when to doing your genealogy. Be sure to make copies of this document, because some of the names don't always stick out as clues immediately. In my family a person listed on a marriage record as a witness later was traced to be the maiden name of the mother once I traced the family back into Virginia.
Tomorrow I will be going over the death records of the county. Thank you again for your support and please send any questions or ideas you might have.
