I am researching my Stewart line in the same area (Neshoba, Scott, Leake Counites) and have found a John and Margaret in my search.
John Stewart dob 3/1857
Margaret Naomi Crecelius dob 12/26/58
Is this your John and Margaret?
If, so, please e-mail me directly-- firstname.lastname@example.org
I have a little more info on them.
