Hi, Once again i am seeking out info on David Johnston. David was born about 1790 in Wilkinson Co., Ga. He was a riverboat pilot and later moved to Plaquemines Parish, La. There he married Hannah Frederika Hoffman they had one son named Alexander Henry JOhnston born about 1841. They are found in the Balize, Plaquemines Parish, La 1850 Census. But after Davids death in 1852, they are no where to be found. If anyone has info that can help---- Please email me at [email protected] Thanks, Tami Johnston [email protected]
