Hello Cousin Justin,
Yes indeed, we can take you back farther than Elias Alexander Garrison, however DNA testing has proven that the lineage I posted to this thread in 2009 is not correct. We are currently stuck at a couple named James & Jane Garrison who first appeared in Carteret Co NC about 1750. You and I descend from their son Isaiah and his wife Elenor.
James (Jane) d. 1771-1783, probably Duplin Co NC
Isaiah (Elenor) d. 1783-1790 Duplin Co NC or Greenville Co SC
John (Delila Baker) d. 1823 Maury Co TN
Elias Baker Garrison (Mary "Polly" Evans) d. 4/18/1875 KS
Elias Alexander Garrison (Margaret Ann Pickering) d. 4/26/1902 Cherokee Co KS
DNA test results have proven that we are not related to the Garretsons of New Castle DE who moved to Orange Co NC and became Garrisons. Some of our Garrison men did spend a few years in Orange Co NC, but no evidence has been found that suggests they ever met or interacted with the other line. The confusion probably began because both lines had a daughter-in-law named Elenor and the two Elenors were combined in error.
I was born in Montgomery Co IL and am a descendant of your ancestor John's brother Zebulon. Let me know if I can be of any more help.
