This profile is part of the Gray Name Study.

John Gray (or Grey), K.G., 1st Count of Tancarville, younger son of Thomas Grey, Knt., of Heaton, Northumberland, etc. and Joan de Mowbray,[1] was born after 1384.[2][3][4]

In August 1415, John was granted the lands that his brother, Thomas (deceased), had forfeited.[4] He fought at the Battle of Agincourt on 25 October 1415.[4] In 1417, John was Captain of Mortagne and the king granted John the castle and lordship of Tilly in Normandy in November of that year.[2][4] John was created a Knight of the Garter about 1418/9.[4][5] On 31 January 1418/9 he was given the comte of Tancarville in Normandy in tail male,[2][4] (Earl of Tankerville).[5] In March of that year he was appointed joint commissioner to treat with the French ambassadors. He served as Captain of Mantes in 1419 and as Captain of Harfleur in 1420.[2] He was also appointed hereditary grand chamberlain of Normandy and governor of Tournay.[5] He was 6th Lord of Powys, in right of his wife,[6] but only held the title for a week, as John died eight days after his father-in-law.[5]

John married Joan de Cherleton,[1] elder daughter and co-heiress of Edward Cherleton (or Charleton), K.G., 5th Lord Cherleton) and his first wife, Eleanor Holland.[2][3][4] Joan was born about 1400/1 (aged 21 in 1421, aged 24 in 1425).[2][3] The date of their marriage is unknown and is estimated. They had one son:

  • Henry Grey, Knt., 2nd Count of Tancarville,[3] born about 1418/9, died 13 January 1449/50, married Antigone of Gloucester and had issue[2]

John was killed 22 March 1420/1 in the Battle of Baugé in Anjou, France,[2][3] and his son Henry was his heir.[4] His widow, Joan, died 17 September 1425.[2][3][4]

I will be using the Magna Carta project's checklist to do a re-review of this profile in the Ellis trail.

I agree the profile might benefit from being rewritten. Unless I have misread it, the Early Life section is showing him as brother of Henry Grey, Grey-291, not his wife's parents as having a son Henry. His own son is shown as a different Henry Grey, Grey-118. That accords with the relationship links on WT.

I have difficulty following the minimalist style of this profile, but it seems to me that it's showing his wife's parents as having issue: Henry - which is his son? I also don't see that his parents are noted with a citation? oops - sorry... found them. They're under "Early Life"

Any objection if I rewrite the biography without all the abbreviations?

The Magna Carta project has identified a potential Magna Carta trail between Gateway Ancestor Rowland Ellis and Surety Baron William Mowbray. This profile will be developed as it is included in the trail to Sir William Mowbray.
