In his garter stall, Henry Marney quarters the Marney arms (at 1 and 4) with Sergeaux (at 3) and the senior branch of Venables (at 4) because of his ancestry:
Sir Robert de Marny quartered the arms of his parents, Sir William de Marny and Catherine Venables. He married Alice le Lacer in 1345. Their son was Sir William (c.1370-1414), of Layer Marney, Essex and Kingsey, Buckinghamshire, a Sheriff of Cornwall, then of Essex and Hertfordshire. He married Elizabeth Sergeaux, daughter and co-heiress of Sir Richard Sergeaux of Colquite, Cornwall (d. 30 Sep 1393). Sir William Marney's heir, Thomas, served under Clarence when
Henry V first invaded
France and was knighted, but he died in 1421, perhaps at
Baugé, leaving the family estates to his younger brother John. The latter's son, Sir Henry Marney KG, was created Lord Marney by
Henry VIII. ==Ancestry==
