I need to update this.This William Killebrew, b abt 1775, son of Hinchey, died by November 1813 in Jones Co. NC, leaving one son, Abner W. and a daughter, first name unknown, who married John Kinsey.Abner W. Killebrew removed to Houston Co. GA where he married Sarah Cox.They had one son, a William, b abt 1846.Abner W. appears to have died by the 1850 Houston census.William, Abner's son, married and had children, all of whom are noted in the 1880 Houston census.This is not my line but anyone interested in the details, can contact me.
As for the William West Killebrews...
(1) Are you referring to William W. Killebrew, b 31 Aug 1806 Putnam Co. GA, d 14 Jul 1884 Erath Co. TX?He was the son of Robert Killebrew Jr. but I've not found anything to prove his middle name was West nor have I found a son named William W. Jr.Have you?
(2) There is also a West Killebrew, b abt 1785 Edgecombe Co. NC, the grandson of Benjamin Arrington.His parents are not known.This West Killebrew is named in two wills, a deed, estate records, census records, etc. in SC but always as "West" and NEVER William West.I'd love to hear from anyone researching this West Killebrew.
