Mary Jones that married Ezikial Brothers can not be the same Mary Brothers who shows up as head of household in 1790 census. She would have been too young to be HofH and also if she married in 1807 her surname would havebeen Jones in 1790.
Caleb and Exikial would almost cetainly have resided in the Gaffney SC Area (now Cherokee Co, then Spartenburg Co)1n 1814-15 when they served in Capt. Michael Gaffney's militia company. This officer was one of the earliest settlers in the area and ran a store there. The town of Gaffney is named for him.
