Well, Luanna is Paulina/Perlina's niece. I don't know anything about the Bass side!
here is what the Apperson Family in America, p 36 says about Luanna:
Luanna Apperson, believed to have been the 4th child of John and Cely Apperson and born about 1815 when the family lived in TN, was married to William Bass in Cole Co., MO, December 28, 1836. In 1830 Cely Apperson was shown by the US Census in Cole County and living nearby were Luanna and William Bass and two children. Luanna probably died about 1848 following the birth of their daughter Mary. The US 1850 Cenus of Bates Co., MO showed William Bass, age 38; Martha, age 22, not shown as a wife; John, age 15; Henry age 14; Elizabeth, age 9; Nancy, age 7; James, age 3; and Mary, age 2. The 1860 US Census Nancy Bass, age 16, in the home of her aunt Minerva Conner. In 1880 Henry Bass was shown living with his aunt, Martha Martin.
