From p30 of Lacies Nobilitie by Sir John Ferne (1586)
Blazon: Per pale, baron and femme; the first gules two bendlets engrailed vert, the second or three barrulets azure surmounted by a bend gules
Ferne presents the coat without any special commentary, besides noting that Gilbert de Gant had chosen to bestow the earldom on his daughter rather than on his son Walter – an unusual choice for the time, and evidently intended to make her more marriageable. Unfortunately, I cannot find any evidence that either of the individuals to whom these arms are attributed existed. It does not seem that, as Ferne asserts, Gilbert de Gant had a daughter named Maud, and even Ferne seems to gloss over the Fitzwright family; it takes less than a full sentence for the earldom of Kyme to pass through the Fitzwrights and to the Umfravilles, whose male line would eventually die out. It might be feasible that Ferne mixed up the names, and meant to write that Lucy, William de Gant’s sister, brought her titles into the Umfraville family; however, the text refers to Fitzwright and Robert Umfravill, Earl of Angus as distinct individuals.
