OK, problem with the Fiske family is that the reconstructions vary with who you believe. The way Moriarty reconstructed it in NEHGR 1932 - 34;
Robert Fiske married Sibilla Gold. (Originally his granddaughter Mary married Anthnoy Fisher and it changed to daughter of Robert's brother Nicholas, because Nicholas's will mentioned Mary and Robert's didn't, and because Candler said in his Candler Manuscript on the genealogy of the Fiske family, that Mary the daughter of Nicholas married ___ Fisher and they adn their children went to New England, and the author of that manuscript was Mary's first cousin once removed.
OK, Robert was the ancestor of most Puritan fanatics who went to New England, though several of his brothers shared his fanaticsm and they were running around England in circles for a while because the executioner was after them.
So Robert had a bunch of sons, and two of them were Thomas and William. William's son John produced two particularly brilliant fanatics; Rev. John Fiske, and William Fiske. They went to Salem and Wenham. Rev. John Fiske served as pastor at Salem briefly and then went elsewhere to practive religion and medicine in the wilderness adn teach college. William stayed at Salem and had Deacon William Fiske, who was one of the jurors in the witch trial.
Thomas had Thomas, whose son Phineas went to Salem and Wenham, and his son Captain Thomas and Thomas's son Captain Thomas were foreman and juror on the jury. I get third cousins and third cousins once removed.
I think that all three of them later signed the admission of error or whatever admitting the error of the Salem Witch Trials.
