This tree on Ancestry.com (http://trees.ancestry.com/tree/28611963/person/12237369411) traces Ann's Jarvis ancestors to the 1500s; however, it presents no evidence for the lineage. Where it gives Ann's parents as Joseph Jarvis and Catherine Bishop, another tree gives them as John Jarvis and Mary Unknown (http://trees.ancestry.com/tree/13821163/person/263558334). I haven't been able to confirm either claim.
