Well, I can't find them in Giles County in 1850. Do you know if they left TN? William Swiney had a daughter age 10-15 in 1840, missing in the William "Swany" household in 1850. Do you know if Susan was 20-25 that year? The census records aren't always accurate, of course. Allen Swiney's age range gave me fits until I found him in 1900, when it shows him born in Dec. 1824 -- making him 75 in 1900 and 25 in 1850. There's a bit of fudging here and there on the earlier records that can really have your running in circles. Fortunately, Allen lived long enough to solve the problem.
