That would be my best guess, and Delilah is most likely the daughter of Van. Van had at least eight daughters. I suspect that Elizabeth Wiggins, Delilah Conner, Hannah Mauney, Nancy Bookout, Mary Harris, and Hollie Virginia Bean were all his daughters but have no proof that any of them were.
My biggest mysteries are who is James Swearingen who appears in the 1820 census of Haywood Co., NC., who is the James Swearingen who appears in the 1820 census of Wayne Co., TN., and who is the James Swearingen in 1820 in Jackson Co., TN.
I believe the one in Jackson Co., TN is the youngest son of Van but have no clue as to the other two. Van had 1 male under 10 in the 1810 census of Lincoln Co., NC. and Van's two older sons, Hugh and William, went to the Jackson Co., TN area about 1810-1811 and Elizabeth (Swearingen)Wiggins and Hollie Virginia (Swearingen) Bean show up there before 1830. Van's brother Richard Cheek Swearingen was there 15 years between 1800 and 1820 and R.C.'s son William was there until about 1830.
