Brandon Fradd, "A New Royal Ancestry for Christopher1 Batt," The American Genealogist 79 (2004):85-99. Fradd has presented evidence that the Jane Harcourt who married about 1430 Thomas St. Barbe was daughter of Sir Thomas Harcourt and Jane Fraunceys, thus providing a descent from King John to Christopher Batt who arrived in New England in 1638.
