There are no records kept by the Cherokee prior to the 1820's, after the syllabary came into use. Before 1800 the only records are historical ones kept by officials of the colonies and then states. Beginning about 1800 there are extensive, but not comprehensive, records kept by the Cherokee Agency and by missionaries. No records are by town or location. Following the treaties of 1817 and 1819 there are two sets of lists, one set is of people who registered to move their families west, the other is of people who took a reservation of land in the area that had been ceded away. The first census of the Cherokee Nation was made in the east in 1835. That same year all Cherokee property was evaluated (the land was held in common, but improvements belonged to individuals).
There is actually information about Andrew Miller, a white man married to a Cherokee woman. He was murdered in 1818; see his bio at https://www.wikitree.com/wiki/Miller-76325 which has links to some of the records.
