Sir Roger de Northwode

2. His son, Roger de Northwood, took an ermine field on which to emblazon his cross engrailed gules. Upon his marriage to Bona de Wautham, heiress of Ralph Fitz Bernard, from which she was know as Bona Fitz Bernard, he was entitled to impale her arms vair (variation on a checked pattern as seen in the photo) on a chief (a field with a bar across the top) gules, 2 mullets of the field (Arch. Cant. Vol. XV. p. 19) with those of his own." The husband's arms are placed on the right (dexter) and the wife's on the left (sinister) of a vertically bisected shield.
