I am also researching this family! My ggg grandmother was Mary Abigail Stoneroad, b Jun 11 1795 PA, d Jan 1870 Iowa, daughter of Lewis and Sarah. Mary Abigail married Jacob Sigler abt 1818 in Mifflin, PA and some of their descendants ended up in Putnam OH (my line). Siblings of Mary Abigail listed as George, Lewis, Valentine, Thomas (who m Margaret Sigler, daughter of Adam and Jemimah Van Horn Sigler), Sarah, Joel and David. All sibling born abt 1790-1807. The one difference I have, is that I have Sarah (wife of Lewis) listed with maiden name of Gardner. I have not been able to find info on her, so perhaps she is really your Sarah Livingood. I sure hope this is a connection, as there is not much out there. Also, I have seen the name "Stoneroad" as originally being "Steinweeg" (the German origin). I have info on the descendants of Mary Abigail if you are interested. Thanks!
