Description: Rectangular, with double astragal edging; three eaglets, their wings outspread, side by side; the initials IW and SW, respectively, to left and right of the central eaglet's head.
Notes: The design is based on the arms of Wynn, of Gwydir Castle in the Conwy valley of North Wales, the blazon of which is Vert, three eagles displayed in fess or. The initials relate to Sir John Wynn (1553-1626/7) who, c.1576, married Sydney Gerrard (d.1632), dating the fireback to c.1576-1626. The conjoined wings of the eagles appear to form heart shapes.
