I would also like to express my appreciation for all the information you have shared on the Knightons.I am not a Knighton descendant, but am researching the Cater family - Frances Cater married Rev. Joseph Knighton.
I can confirm one child of Joseph Knighton and Frances Cater which is Rev. John Knighton, who was a Baptist minister and at one time preached in Conecuh County, Alabama.
I descend from George Cater who left a will in Sumter County, South Carolina probated in 1821.He mentions as his children, William Cater, my ancestor, and Frances, who married Rev. Joseph Knighton.I have a copy of a letter written between two grandchildren of William Cater (d1835, Monroe County, Albama) recounting some of their Cater relations.The letter was written by Leory W. Roberts (1844-1931) of Rockdale, Texas to Douglas John Cater (1841-1931) of San Antonio, Texas on November 1, 1914.After recounting the children of their mutual grandfather, William Cater, and their marriages, Leroy Roberts mentions other Cater cousins he has known as follows:
"John Knighton was an other Cousin of theirs (his and Douglas Cater's parents) a hard shell Baptist Preacher.I have heard him preach often and his Shell was hard Sure enough.He used to say I am going to hew to the line and I dont Care where the chips fall and It would(n')t be long before he would rout the Methodist.He would always shed his coat when he got too warm."
I know the relationships I've attempted are rather confusing so I offer the following as clarification:
1.George Cater, Sr. (d. 1821, Sumter County, SC) .....2.William Cater (d. 1835, Monroe County, AL)m. Catherine Collins .........3.Susannah Cater (c1806-1849)m. Leroy Roberts ..............4.Leroy W. Roberts (1844-1931), who wrote the letter above .........3.William Green Cater (1815-1882) ..............4.Douglas John Cater (1841-1931), one of the correspondents mentioned above .....2.Frances Cater m. Rev. Joseph Knighton (d. 1837) .........3.Rev. John Knighton
