Mary Knight was married to Hugh Hutchins according to Hugh Hutchins of Old England by Jack Randolph Hutchins. Geni gives her birth name as Treat, with many connections but no sources. No one with the surname Treat is in the index of Hugh Hutchins of Old England, so that seems unlikely given that she is the wife of the titular person.
Worse still is Harms Family Tree, created by larryharms_1 on Ancestry. According to that, her parents are Arthur Hutchins (born 1626 • Broadwindsor, Dorset, , England Death 13 Apr 1690 • Broadwindsor, Dorset, , England) and Emma Hutchins (born 1628), which sounds ridiculous as her parents, but almost certainly people who belong on my tree even if Harms botched the maiden name.
Hugh had an uncle named Arthur, but he died as a child (born 4 MAR 1653 DEATH BEF. 14 MAY 1657). He is the oldest Arthur Hutchins I currently have on my Ancestry tree.
