I am trying to track a relative who is listed in the 1850 census in Boone Co., MO. Among his neighbors are siblings, parents, cousins. By 1860 the extended family is dispersed to 3-4 neighboring counties, and I can find everybody except my guy. I am confident he remained in the area past 1860. He does not appear anywhere in the ancestry.com index and I have browsed the census pages in the communities of his relatives to no avail. So a few questions: what percentage of people might have been missed by the 1860 census takers? On the chance he was no longer in the area, what percentage of people are omitted in ancestry.com's index? Any clues on how to proceed? Susan Moeur <[email protected]>
