I am a direct descendant of the Sisty family and am in possession of the Sisty family bible and some photos and other artifacts including hundreds of pages of geneology research. My mother was Betty Jane Sisty, her father one of the many William Lane Sisty's -he was the son of George L. and Mara K. Flansberg. Sadly, I have no more information on the early John Sisty mentioned in the post, as that is where that family line stops. However, I have many pages about his descendants, the marriage and relationships with the Crockett family and others.
I am meeting a new-found cousin from the family related by way of two Sisty's both of whom married into the Flansberg (Flensburgh) family. It would be great if we could pool our information to make a more complete picture of our family history.
