Do you by any chance have any information on the other Smith Abernathy (b.1755 Granville County, NC, lived later in Lincoln Co, NC by 1790-c 1809, then Rutherford Co., NC c. 1809 -appears there in1810 census- to c. 1815, when he moved to Tennessee) ? I am particularly interested in any evidence as to the parents of Martha B. Abernethy (24 Nov. 1788-24 June 1840), who married John Carson Gettys in Rutherford Co., NC 9 Nov. 1809. They are buried in the Price cemetery in Rutherford County, NC. Martha is generally credited as being a daughter of this Smith Abernathy due to his presence in Rutherford County, and the fact that three of her sons were named Smith, Alexander and Robert Gettys(after her presumed father, brother and grandfather). However, beyond this naming pattern and general geographic proximity (and a later reference to one her brothers being a minister in an adjoining county-which her presumed brother Alexander Abernathy was in Burke County, NC) there seems to be no real evidence of a relationship.
There is an interesting biographical sketch , focused on the ministerial career,of Smith Abernathy's son Alexander (13 March 1790-31 Aug. 1866, m. Elizabeth Wilkie in Rutherford County in 1814) which traces Smith Abernathy's several moves within Lincoln and Rutherford Counties 1790-c. 1815, when he moved to Tennessee, but frustratingly does not give names of Smith Abernathy's wife, other children or where he moved in Tennessee.
