Brother of John S. Ficklin
1830: purchased land in the current Lawrence county seat of Jackson with improvements including buildings and a grist mill.
1831, John and Thompson became partners in a mercantile business in Jackson, Arkansas
On April 12, 1835 an advertisement in the Arkansas Gazette dissolves a business partnership between Thompson and Charles Rapley in Little Rock, showing the connection rural Arkansan merchants had with surrounding cities and hubs of commerce. Thompson dies one month later of cholera in New Orleans, leaving one-third of his estate to John and the rest to his widow, Mariah. Ficklin’s relationship with Thompson’s widow is significant because she marries Archibald Yell, the future governor of Arkansas on July 7, 1836.
