Sorry but I don't know this family.Sadlers lived and still live in the Alexis, N.C. area of Lincoln and Gaston County, N.C.From what I can estimate is this Abernethy family lived from Sherrills Ford to Mountain Island (Hwy.16) and branched out into the Alexis/High Shoals (Hwy. 27) area.If I come across any information, I will post.Some Abernethys along with Goodsons and Stroups went west in the 1830/40 era.Some settled in Murphy, N.C. and others went to Bartow County, GA. Some branched out into TN. and others went to Alabama from TN.Also, some of these Abernethys went to Spartanburg, S.C. and their relatives ventured to Arkansas.This is the general knowledge I have but I basically have stayed with the N.C. Abernathy/Abernethys.Be reminded that there were many David Abernethys and unfortunately (or maybe fortunately) many went in the ministry.They certainly didn't get rich from this but started missions/churches to other parts of the country. There should be a Methodist/Episcopal minutes book somewhere but I haven't found it.
