That marriage info found https://familysearch.org/
If there had been a Texas-connection, more records would have been available for research. For me, the "key" beginning were the marriage records found on your family tree. Your ancestor wed G. W. Taunton (28 Dec 1882). Lucinda wed Samuel S. Tyler (30 Aug 1891). Elizabeth aka Bettie wed Edward Davis (17 Dec 1885). Consider including a url to your tree on future requests for assistance? Once I had located the marriage place, I simply backtracked using the wildcard option for the surname. Did you find Elizabeth's widow pension application? FYI! Death listing familysearch: Mrs. G. W. Taunton (8 Dec 1949) mother's maiden identified as Hardaway.
