I believe her surname was Mize and that her mother was unmarried, but so far no proof other than that Lewis and Jesse Mize were also Keziah's children (born in 1835 and 1837). Keziah appears to have married Jesse Siner later as his second wife. My ancestor was Elizabeth Ann Mize who I think was Keziah's older sister. Emsley married Elias Bowman in 1879, apparently her third husband, and lived in Jonesville VA.Elias was much younger. Emsley had sons William, John, and Robert Shiflett/Shipley and probably other children too if I can recall correctly from prior research.
I have been trying to find definitive proof that Elizabeth was the daughter of Randolph Mize and Martha Matthews, who moved from Mecklenburg County VA to Wake County NC,then on to the Clemmons, NC area which was Rowan and then Davidson County, and finally to Wythe County, VA, where Martha "Patsy" appears on the 1830 tax list and census. Emsley was born in Davidson, and Lewis and Jesse in Wythe. Elizabeth married Odom Bunn in Rowan (Davidson) in 1822 and moved to Carroll County VA and then to Sullivan County TN. Some Mizes remained in Davidson and some moved to southern Illinois. Keziah and Jesse Siner probably married in Wythe and lived in Scott County and Washington County. Lewis and Jesse lived in Washington and Lee Counties and also spent time in Sullivan County. It is a very difficult family to piece together.
