Armorial arms of james quartering james and moriskines plate 1790

Chinese export porcelain armorial plate featuring the arms of James quartering James and Moriskines, Quianlong, c.1790.
From Chinese Armorial Porcelain, Vol. II, by David Sanctuary Howard, page 578:
“The arms are of James, Argent two bars embattled counterembattled gules, quartering, Argent a chevron between three fers-de-moline sable, quartering Moriskines, Barry wavy of six argent and azure on a chief or three swallows volant sable. The crest is of James, Out of a ducal coronet or a demi swan with wings expamded argent, as also the motto ‘Fide et constantia’.
These quarterly arms are illustrated exactly in the 1663 Visitation of Kent, which shows three generations to Sir Demetrius James of Ightham Court in Kent, from William James of Ightham (whose younger brother was John James of woodesborough who married Susannah Vanderwall of Antwerp and had five sons living in 1620).
Sir Demetrius was knighted by Charles II in 1665 and his grandson was William, High Sheriff of Kent in 1732. He married his cousin Elizabeth, daughter of Haestrech James of Reigate, and had two surviving sons: Richard, for whom this service was possibly made, born in 1746, a Colonel in the Army, who married in 1806 Letitia Gibbons but died the next year without issue; and the Reverend Demetrius, Rector of Ightham, who died in 1781. A bookplate (Franks Collection 16277) c.1810 has exactly these quarterings and crest (although different motto) and is engraved with ‘Richard James’.
William, High Sheriff in 1732, had a younger brother, also Demetrius, a Colonel in the Army whose daughter Elizabeth married Charles Grevis, and their son, Demetrius Grevis, inherited the Ightham estates in 1807 and changed his name to James, the James arms thereafter quartering Grevis.”
