The only David Johnson found in 1850 Tallapoosa Co, AL does not fit the family you showed. Here is the info as found in the census. 1850 Tallapoosa Co, AL census, Township 21, pg 28, dwelling/family 37, 17 Oct 1850 JOHNSON, David 38 (1812) m w farmer 400 GA JOHNSON, Harrett 31 (1819) f w GA cannot read or write JOHNSON, Mary C. 14 (1836) f w GA attended school within the year JOHNSON, Martha 9 (1841) f w AL attended school within the year JOHNSON, Benjamin 5 (1845) m w AL JOHNSON, William D. 3 (1847) m w AL JOHNSON, Sarah J. 4/12 (1850) f w AL There are many David JOHNSONs in the state of AL at that time, so if you had an approximate age it would be easier to look through them to see if they lived somewhere else. Sorry, could help more, John
