Coggin(s) - 1860 TN census

Have been searching for the following Coggin(s) family during the 1860 census.They were in Polk County, Tennessee in 1850:

Coggin, Owen - 32
wife Sarah -23
children - Susan - 10
Nancy - 8
Mary - 6
Sarah - 4
Thomas - 1

I have found them again in the 1870 TN census in Roane County and in 1880 TN census in Meigs County.Have been unsuccessful in locating them in 1860.Would truly
appreciate any help. Thank you.
