Two groups that work on promotion of Historic Vandalia are joining forces and will elect offices this evening. The Friends of the Vandalia Statehouse has now merged with the Vandalia Historical Society. The group will meet this evening at 5:30 pm at the Vandalia Statehouse, where they are planning to elect officers and board members for their new merged group. One of the charges for the group is raising money for new windows at the Vandalia Statehouse and to help maintain it along with the Little Brick House.
