Biddie was the daughter of John's son charles. John Vansill married Sarah King and after her death married again and then married Susan King. I just received the names of the children for these marriages .Sarah's children were Mary dob 2-14-1856, Melissa J. dob 12-9-1858,Rhoda E. dob 10-14-1860,Joseph W. dob 5-24-1861, Lory S. dob 1-4-1863, Spiena dob 7-16-1864, Ida MArgaret dob 1-8-1867. Susan's children were: Edward dob 11-1877, Susan Louise (Lula) dob 8-31-1875 and William dob ? Hope this helps.
