The problem with Wiki is that it is impossible to verify actual sources with faulty information that has been accepted for decades because actual sources that clarified information were not available. There is some faulty information within some of the visitations that have greatly confused the issue of John Foote and Robert Foote of Royston. There is no Robert Foote of Royston, John Robert, Robert John or Sir Robert or Sir John of Royston. There is a John Foote, Yeoman and Chandler of Royston, He was not knighted, but it appears he did bear arms, Ar. a chevron Sa, in dexter chief a trefoil slipped Sa. He had 4 children that are known, ales or alice, elizabeth, Robert (later known as Robert Foote of Shalford, Yeoman and fishmonger), and John, grocer of London (sometimes also called John Foote of Royston). Nathaniel Foote the settler was son of Robert of Shalford, and Sir Thomas Foote, Lord mayor of London was son of John Foote Grocer of London. These facts are clear from the wills of John Foote of Royston, Robert Foote of Shalford, Elizabeth Brooke (Mother in law of Robert Foote of Shalford AND John Foote of London), John Foote of London and Margaret Brooke of London, wife of John Foote grocer of london.
The Clandon Park Collection of the national trust contains a painted copy of the Genealogy of Sir Thomas Foote that hung in his house with arms that shows the Arms displayed and quartered by his father and grandfather, although the name of the grandfather and the quartering are missing.
