The following is from page 169 of AVERITT KINSMEN: Elisha Averett. (Twin) born 12 Dec.1810, Maury County Tn. Died 22 Oct. 1890 in Glendale UT. Married (1) DORCAS WILLIS(born 1 Feb. 1810 in Gallatin, TN.) They had one son, William, born in Hancock Co., Il. A second child died with the mother at birth. Elisha married (2) Sarah Jane Witt, a stepdaughter, born 1 Feb 1831 McLeansboro, Il. on 19 Jan.1846. They had 13 children. No mention of a Robert Averett in connection with Dorcas Willis. Hope this can be of some help.Dorcas is to me an unusual name, but there could have been more than one considering the time difference (20+ years) between yours and mine.
