He married (1st) ELIZABETH LOUCHES, daughter and heiress of William Louches, of Great Milton and Chislehampton, Oxfordshire. They had one son, Richard, Knt., and one daughter, Alice. He was heir in 1372 to his uncle, Thomas Camoys, Knt., by which he inherited the manors of Trotton, Barcombe, Broadwater, and Elsted, Sussex, Great Stukeley, Huntingdonshire, Bekerton, Norfolk, Tansor, Northamptonshire, etc. In 1375 he was granted a weekly market at Broadwater, Sussex. The same year his maternal uncle, William Latimer, K.G., 4th Lord Latimer was granted various tenements and houses in Calais by the king formerly held by John Dayre, with remainder in male tail to Thomas Camoys. In 1378 he disputed the advowson of Broadwater, Sussex with Adam de Hartingdon. He was a legatee in the 1381 will of his cousin, William le Latimer, K.G., 4th Lord Latimer, by which he inherited the manor of Wotton, Surrey. He presented to the church of Wotton, Surrey, 1382, 1383, and 1392, and Lasham, Hampshire, 1392. He was one of the liveried personnel of his brother-in-law, Edward Courtenay, Kim, 11th Earl of Devon, in 1384-5. He saw military service in Castile under John of Gaunt. He was summoned to Parliament from 20 August 1383 to 26 Feb. 1420/1, by writs directed Thome Camoys ch'r, whereby he is held to have become Lord Camoys. He was excluded from court in Jan. 1388 by order of the Lords Appellant. In 1389 he made a settlement of the manor of Honydon or Camoy's (in Eaton Socon), Bedfordshire. In 1399 he was granted the bailiwick of the forestership of Alice Holt and Wolmer, Hampshire by the king "as Ralph de Camoys his grandfather had in the time of Edward III." The same year he and his son, Richard, were jointly granted custody of the castle and town of Porchester, Hampshire. In 1400 he manned a ship for service against the Scotch and the French. In 1405-6 he unsuccessfully claimed the manor of Eling, Hampshire against the warden of Winchester College. He married (2nd) after 3 June 1406 ELIZABETH MORTIMIER, widow of Henry "Hotspur" Percy, Knt., styled le Fitz, K.G., K.B., Justice of Chester, North Wales, and Flintshire, Warden of the East Marches, Captain of Berwick on Tweed [see PERCY 12 for issue of that marriage], and daughter of Edmund de Mortimer, Knt., Earl of March and Ulster, by Philippe, daughter and heiress of Lionel of Antwerp, K.G., Duke of Clarence, 5th Earl of Ulster (younger son of King Edward III of England) [see MORTIMER 13 for her ancestry]. She was born at Usk, Monmouthshire 12 (or 13) Feb. 1370/1, and baptized 16 Feb. 1370/1. She was a legatee in the 1380 will of her father. They had one son, Roger, Knt. [Lord Camoys].

In 1433 he ceded his rights in the manors of Stukeley (in Great Stukeley), Huntingdonshire and Barcombe, Broadwater, and Trotton, Sussex to Roger Lewknor and his wife, Eleanor, niece of the said Roger.

      iv. EDMUND MORTIMER, Knt., of Narberth, Pembrokshire, and St. Clear (in Trayne), Carrnarthenshire, 2nd son, born at Ludlow, Shropshire 10 Dec. 1376. He was a legatee in the 1380 will of his father. Edmund was taken prisoner by Owain Glyn Dr, Prince of Wales at the Battle of Bryn Glas fought at Melienydd, Radnorshire 12 June 1402. King Henry IV of England refused permission to pay a ransom, in consequence of which Edmund joined the rebellion of Owain Glyn DWr. He married about 30 Nov. 1402 KATHERINE FERCH OWAIN GLYN DWR, daughter of Owain Glyn Dŵt, Prince of Wales, by Margaret, daughter of David Hanmer, Knt. They had one son, Lionel, and three daughters. In 1404 King Henry IV granted the Welsh lands of Edmund Mortimer, then in rebellion, to Thomas Carew, Knt. for life. SIR EDMUND MORTIMER died during the Siege of Harlech Castle (or immediately thereafter) apparently in Jan. 1409. His widow, Katherine, and their children, together with her mother, were taken to London and held in custody by the king. Katherine and her two unnamed daughters were buried in late 1413 in the church of St. Swithin, London.
