The Maryland Society of Sons of the American Revolution have provided the Maryland General Assembly Assessment Record for Charles County, 1783 (and other years), providing insights into the conditions of the Maddoxes’ life at the time… http://www.mdssar.org/sites/default/files/archives/1783taxlists/Charles_Co_MD1783OPT.pdf.
