In Holcomb's Rutherford marriage bonds I do find a 1796 marriage of a James Morrow and an Elizabeth Suttle.Your "Elizabeth Baxter Suttle" seems too early to be a daughter of the William Baxter (1759-1852) of Caroleen, who was the patriarch of the Baxter line in antebellum Rutherford (he is said to have arrived there in the late 1780s).Two of his children did marry children of George Suttle (1766-1816) of Floyd's Creek.They were William Baxter Jr. (1796-1838), who married Nancy Suttle (1802-ca.1882) in 1821, and Sarah Baxter, who married Benj. F. Suttle (1800-1859) in the same year.There were other Suttles in Rutherford besides George though.His father, Joseph (b. ca. 1727 in VA), came to North Carolina in the late 1760s and died intestate in Rutherford in the mid-1780s.His wife was named Mary Doggett by the way.
If you want to trace the Suttles, the first thing you should do is obtain a copy of Col. Wm. Emmett Reese's The Settle-Suttle Family.Try to get one on inter-library loan at your public library. If this book doesn't answer your questions you'll need to go to the primary sources.
I just recently visited the old Suttle graveyard where George Suttle, his wife, Wm. Byars Suttle and Nancy Suttle are buried.It's neatly situated on a hill.I'd like to try to locate where the plantation house was -- it burned in the 1940s.
