I found a family in the 1860 census in
Clay, Dunklin, Missouri
The Household members were
Lydia J 6
Then I found in 1862 an Osborn Fuller joined the Co B, 1 Missouri Company in Feb 1862. He is then listed as “died April 10, 1862. This was a Missouri Co. that fought on the Confederate side.
I also found this same family in 1850 in District 6, Dyer, Tenn, with an older son Green who would be 23 in 1860 so he is probably married at the time of the census.
If you think these people are who you are looking for, I can email copies of the above information.
