The Memento Collection contains mementos donated by former governors or their families and represents every administration since the house was built in 1856.
The Memento Collection was developed by First Lady Jean Daniel in the 1960s. Mrs. Daniel contacted family members of past governors and asked them to donate an item that was either used in the Mansion while the family lived there or a personal family item. A tradition was established where every successive governor would leave a memento representing their term in office to be displayed in the house.
