Hi, I am seeking information on David JOHNSTON b. 1790 in Wilkinson Co., Ga (according to a copy of his will he stated he was from Wilkinson Co., Ga but had no brothers nor sisters alive at the time of his death). He moved to Plaquemines Parish and married Hannah Frederika Hoffmann in 1840. They had one son named Alexander Henry Johnston. David died in August 1852. David was also a riverboat pilot. I am at a dead end on this family.
