From the Surrey Coats of Arms:

ILLINGWORTH of Mitcham.
Arms: Argent a cross flory Gules between three escallops Sable.
From brasses in Mitcham Church to Richard Illingworth, (d.1511), and to Ralph Illingworth, (d.1572). (SAC xxx 94)
But at (SV1530), William Illingworth of Mitcham, is recorded, possibly in error, as bearing Argent a fess flory and counter flory Gules between
three escallops Sable. *

* Crest. Burke gives for Illingworth, of Surrey: Within a crescent Argent a cock crowing Sable. (BGA)
