Daniel Henry Plough appears in the 1850 madison census at age 12 in the home of Henry and Ann Plough. A son age 2 appears in 1840 census (assume its the same person). What Happened to this family after 1850? Henry and Ann were both 71 in 1850 so possibly dead by 1860, but Daniel would have beeeen only 22 in 1860 and I cant find him anywhere in US!!! Anyone know anything? Many thanks.
