My husband and I just received our new Cunningham family history book and it has a wealth of information about the Cunninghams, including Mary J.Are you interested in the Sivills/Savells or the Cunninghams?
Info from the book:
Robert T. (Rat) Cunningham, born 1815 in Albemarle Co., VA., d. 1884 in Trigg Co., KY.Married Mary J. Sivels, b. 1822 in KY., d. 4/23/1890, dau. of Thomas and Elizabeth Sivels from VA.Mary J. was a sister to Elizabeth Sivels who m. Robert's brother, Mickens Carr Cunningham.
Info from my research:
Thomas Sivels/Sivells/Sivills was b. July 18, 1773, the son of James and Elizabeth Sivells.Betsy, his wife, was b. Dec. 16th, 1779.Their children were:Ruth, b. Sep. 10, 1799, James W., b. Nov. 1, 1802, John M., b. May 12, 1806, Sallie S., b. Feb. 15, 1809, Amelia and Louvinia, twins, b. Sep. 10, 1812, Betsey, b. April 23, 1815, Thomas W., b. March 25, 1818, and Mary J., b. Sep. 16, 1821 (my date differs from the C'ham history book but came from an excerpt of their family Bible found in the book Savils/Sivils Family Records of Trigg Co., KY. written by Barbara Smith).
Thomas Sivels' wife, Betsy's maiden name is thought to be William/Williams.
In an 1820 census for Trigg Co., KY. for Thomas Savells, which gave only numbers, there are also 2 males ages 16-26 who were not identified by the family Bible.
Hope this is of some help to you.This family came from Norfolk Co., VA.
