I read with interest the information on your web site. I am somewhat confused about Elizabeth Foster being the wife of Charles Cox II. In my Family Info., I have an Elizabeth (Betsy) Basden marrying a (?) Cox and having a daughter named Miriam who married Hershal Mashburn, Sept.11, 1851 in Onslow Co., N.C.. Please note the following Will information of Betsy's brother, Kinchen Basden: 
BASDEN, KINCHEN dec. (PR) 1. Bill, Sept. 12, 1879. Basden died in Hardeman Co., Tenn., 1862, leaving no children but these following brothers and sisters (1) Barbary Foster dec. who left one child, W.H. Foster (2) Sally Foster dec. who left one child, William Foster dec. who left children Jane, Kinchen, Sarah Parker, Jane Riley, Anna, Nancy, John, Powell, Monroe, Dolly, and William Foster. (3) Betsy Cox dec. who left one child, Marion (wife of Hershel Mashburn) (4) Polly Bradham dec. who died in Illinois many years ago. 

Citations to Kinchen Foster of Hardeman Co., Tenn; Sarah Parker and husband, John, of Texas; Jane Riley, Rena, William, Nancy, John, Monroe Foster, and Minerva (wife of Richard Powell) all of Van Buren Co., Texas; Dolly Williams and husband Nathan, p.o. unknown. Elizabeth(Betsy)Basden's sister, Sarah Basden was married to a FOSTER and had one son, William B. Foster, my GGGrandfather. 
I am trying to determine William B.'s father and Sarah Basden's father. Should you have any information related to this, I would appreciate very much knowing of it. Evidently another of Betsy's sisters, Barbary, also was married to a FOSTER.

Also, if you have any clarification for Betsy Cox's maiden name I would like to know about it.

Sincerely,
