Had the privilege last nite of attending the ceremonial opening of the National Archives exhibit on the Civil War Sesquicentennial at The Henry Ford in Dearborn. It is an amazing and large exhibition of materiel! Kids should definitely like it, given its videos, interactivity, and artifacts like the 1860 census book in which U.S. Grant is found.
Besides the special NA room, THF has its own Michigan-related exhibit. Featuring an 1861 artillery piece and other artifacts, the centerpiece is the Loomis Battery. That alone is well worth the trip.
And an amazing fact: the exhibit was opened with a symbolic ribbon cutting by Mr. William Clay Ford, Jr., who used an original foot officer’s sword from the Museum collection. The sword belonged to Captain Joshua Slayton of the 13th Michigan, who hailed from Eaton Rapids. His picture is here: Slayton
