Hugh Crockett had a daughter, Nancy Agnes, born about 1778 who married Joseph Potts 08 Feb 1799 in Botetourt county VA. They moved to Williamson County TN between 1800 and 1810 as did the family of Nancy's brother Samuel Crockett.
Potts died in Williamson Countybefore 1813 and Nancy married Riley Slocumb 21 Dec 1813 there.
Riley Slocumb and Samuel Crockett moved their families to Boone County, Missouri Territory just before 1820.
Nancy died before 1830. I have seen the claim that her death date was 30 Jul 1820 in Boone County, buthave not seen proof.And that Riley Slocumb died 28 May 1847 also in Boone County.
Children of Nancy and Riley were:
Nancy Slocumb, 1814 - 1836, married to Joseph M. Gray, 27 Mar 1834, Boone Co. MO
Robert Crockett Slocumb, 1817 - 1885, never married.
Cynthia Slocumb, 1818 - 1901, married Elliot P. Cunningham, 1845 in Boone Co. MO
Robert Crockett Slocumb and Cyntha Slocumb Cunningham are found on Find A Grave in Elmwood Cem., Mexico, Audrain County MO.
