Jarvis family 1815 Georgia probably went to TN by 1830

Hi!  I'm new to this site.  My ggggrandmother was Myra Jarvis, born 1815GA.  I have no clue as to her parents.  There is a huge amount of info on Jarvis families out of NC but can find no GA Jarvis/Gervais family w/ children during this time period.  Myra may also be spelled Mariah, Mira, etc.  She married Charles Bates of CT in Fayette Co TN.  They ended up in Allamakee Co Iowa where Myra died in 1864.
Thanks!
