I'm descended from "F" on your list, Fabious Mitchell through Josephus A. Mitchell. I'm trying to find out more about his daughter, Rowena Alice Mitchell b. Jun 1873, and her husband, Wade Hampton Spangler b. Jun 1872, both of Floyd County, VA.
I can't find a record of them after the 1910 census, until Rowena shows up in a city directory in 1924, listed as widowed. Not sure if her husband was a casualty of WWI or if something else happened to the family. Any leads would be appreciated.
