Nettie Graves is actually the daughter of Loffie Farrington and George Irvin Wallace.
Loffie was married to Reverend Norman G Moody so this is where the confusion is taking place I imagine.
Idalia Mary Rains was married to Norman after Loffie
Also Syvellia Hight and Ettie Moore are not Idalia's children but rather Celia Moody who was also married to and either divorced Norman or passed away sometime in the early 1920's-- I stumbled on this in my quest to find out more about Loffie Farrington
Thanks!
