It's possible that a family bible, set of letters, or other artifact from your family is housed a significant distance from where your ancestors actually lived. An aunt of mine lived her life in western Illinois. A quilt she made in the late 19th century is in a museum in Michigan. The reference came up on a Google search and I almost ignored it because the location "wasn't right."
It is hard to tell where ephemera from your ancestors ended up.
Tombstones are usually in the "right place." Other items can be up for grabs.
