I am not a descendant of the Chenault Family but my beloved wife, now deceased, is the grandaughter of Maggie Eugenia Chenault of Caroline Co., VA. Somehow in my research I came into possession of a copy of the death certificate of William Shephard Chenault of Kidds Fork in Caroline Co., VA. whose wife was listed as Lucinda Chenault. William was born Oct 15, 1864 and died July 28, 1951 at the age of 86. Although he resided in Caroline Co., VA he died at the Medical College of Virginia in Richmond, VA. The names of the parents were listed as James Chenault and Susan KellyCould this by chance be the grandfather of your wife?
Also I have a copy of the marriage certificate of William Robert Chenault to Bessie K. Sharpe. The parents of William Robert are listed as William S. Chenault and Lucinda Chenault.
Also I have a copy of the birth certificate of a William B. Chenault on September 4, 1893 and the parents are listed as William Chenault and Lucinda Chenault.
