I to have seen the reference to John Afflack and his incarceration. I have not seen any actual records. The best information I have is that he was the father of your John Jones Afflack. Also I have been told that it was actually his daughter that died. He was found not guilty of murder but guilty in the unlawful and felonious slaying of his daughter Sarah. He was sentenced to 16 months and his left hand was branded with the letter M. I beleive that Nancy Taylor Afflack was still alive in 1850 where she is found living with her daughter Prudence Luster in the census. I know nothing of the Joplin's. Only that John Jones married Susannah Joplin. Sorry!
