Hi John, I can see where it is confusing. I know that there were a John Wesley and William Blanton Crisler ( I believe this is actually the accurate spelling). I have found Civil War record of John Wesley Crisler serving in Georgia during the War. I have also found John Wesley Teasley (Joshua Teasley's son) serving in Mississippi as did his brother William Blanton. Anna and Joshua were the children of William.(although there is question about Joshua)Anna married Wesley Crisler and Joshua married Mary Polly Crisler who were brother and sister. It appears that Anna and Wesley went to Mississippi before the war but their son John Wesley Crisler did not, because he served in Georgia. Joshua and Mary Polly stayed in Georgia, but there son John Wesley moved to Mississippi where he met and married his wife Margaret Eveline Cooper. He served in the war in Mississippi. I believe that the name John Wesley was probably the full name of the first know ancestor John Teasley born in 1702 in Isle of Wight, Virginia. It would not be uncommon for that name to be used quite frequently.John Wesley Teasley had a son named James Oscar Teasley who is my husband's gggrandfather. My husband's father is named for him. I know that he is definitely not descended from Anna. If you would like more information concerning this I know that Kyle Williams has quite abit. His research seems the most accurate that I have studied. Some believe that Joshua was the son of JohnIII Teasley, but after careful study of the migration of these families it appears that Joshua is actually connected to William, although there is no absolute written fact to substantiate it. It appears that your John Wesley Teasley may have served in war in Tennessee a long with several other Tennessee Teasleys including his brother Francis Marion and several of his brother Allen J. Teasley's sons.
All of my information may not be completely accurate but I do know that my husband definitely does not descend from Anna Teasley
