Military (Sir John de Meaux)
Fine-grained creamy limestone, almost certainly Magnesian
d. 1377
On heraldic chest, west end of north chapel.
Worn and with parts missing, e.g. sword, dagger, fingers.
Straight legged. No shield present but he wears a coatarmour with the remains of de Meaux heraldry in shallow relief; gauntlets; bascinet and aventail; horizontal hip belt (lozenge mounts) but sword and dagger lost; head on helm; plate limb defences; lion foot support. Funeral armour: a great bascinet associated with the tomb survives. Now in the collection of the Royal Armouries (Fig. 120), a replica hangs above the tomb.
The north chapel was in use as a school by the late eighteenth century (Gough 1786–96, I.2, p. 180), ‘with a knight in armour much defaced by the boys’. By the 1820s, the tomb had been moved into the ‘belfrey’, T. Thompson, Ocellum Promontorium or short Observations on the Ancient State of Holderness, Hull (1824), p. 254. It had been returned to the north chapel by the 1840s (Poulson 1841, II, p. 12). The significance of the bascinet was already appreciated by the end of the eighteenth century (de la Pryme, p. 217). Sir John de Meaux’s will survives, giving instructions for his funeral and asking for burial in the lady chapel at Aldbrough (Test. Ebor. I, p. 100). See also Section 3f.

St Bartholoew’s at Adbrough, between Withernsea and Hornsea has two interesting effigies. A knight’s effigy of c. 1390, Sir John de Meaux or de la Melsa. Shields on the tomb chest. Including Hastings, Roos, and Marmion. Three of my favourites. The heraldry is a bit worn unfortunately. The head rests in a great helm. Hanging above is a repro of a bassinet of the period. The original is in the Tower of London. The Armouries pay an annual fee to the church.
The other effigy is probably Maud the wife of John de Meaux. She is under an arch between the chancel and the chapel where he is. She has the same griffins, or rampant lions, of Meaux on her cote. There is a small canopy above her head. Again she is on a chest. It would be interesting to know the details of the construction of these tombs as they are near each other but not together. And her identification is not perhaps certain.

John de Meaux - before 1311–1377
"On the 4th May, 1353, license was granted to Sir John Meaux, Knight, to have the bones of Godfrey Meaux, his great-grandfather, John Meaux, his grandfather, Godfrey Meaux, his father, and Scolastica and Joan, his sisters, removed from the church of Aldborough to the priory of Hautemprice, in consequence of the encroachments of the sea : they are to be buried in a place in which, as we understand, Sir John himself intends to be interred. Sir John Meaux, to whom the license was granted, was buried at Aldborough, and not at Hautemprice, in 1377. A rich altar tomb, which bears his effigy, commemorates him, ..."

The identity of Beatrice will always remain in doubt, but there is a distinct possibility that she was Beatrice de Meaux, daughter of Sir Godfrey de Meaux and his wife Scholastica de Gayton and sister of Sir John de Meaux.

While most sources agree that Maud was known as Maud de Sutton ... there's confusion with her parents. Richardson (2011), calls her "Maud Grey," while Lewis (n.d.) calls her "Maud St.John," widow of John Meaux, whose father is supposedly Sir Godfrey de Meaux.
According to Blashill (1896), it was John Meaux's (d.1377), sister and heir ... Alice, who married Ralph Hastings. Meaux's father was another John. (The last Godfrey (Godfridus) in the family, lived during the late 1200s).
