Summary for William de Ros, 3rd Baron Ros of Helmesley:

Relationships:

Parents:

• Father: William de Ros (d. 3 Feb 1343, buried in Kirkham Priory, Kirkham, North Yorkshire), 2nd Lord Ros of Helmesley (FMG lists his grandfather as becoming Lord Ros of Helmesley during the Parliament of 1299, Lundy labels his title as Lord de Ros of Helmesley citing Burke's Peerage, Baronetage & Knightage, 107th edition)
• Mother: Margery de Badlesmere (c1306 - 18 December 1363, according to Lundy)

Siblings:

• 2. Thomas de Ros (b. 13 January 1337 at Stoke Albany, Northamptonshire, d. 8 June 1384 in Uffington Lincolnshire, m. Beatrice de Stafford, widow of Morice Fitz Thomas, Earl of Desmond)
• 3. Margaret de Ros (FMG supports)
• 4. Matilda de Ros (labeled by Lundy as Maud de Ros, d. 9 December 1388, m. John de Welles, 4th Lord Welles)
• 5. Elizabeth de Ros (Lundy supports, saying she married William la Zouche, 2nd Lord Zouche of Haryngworth)

Spouse:

• Margaret de Neville (12 February 1341 - 11/13 May 1372)

Children: None known.

Basic Information:

Birth: 19 May 1329 (according to Lundy, FMG, and Castelli)

Baptism: Unknown.

Marriage: 8 May 1341 (date that the license to marry was issued, presumably by the King)

Death: Before 3 December 1352.

• English Wikipedia says that he died on the way to the Holy Land, which would be quite odd, given that no crusades against Saracens, etc., were taking place during this period (the Alexandrian Crusade wouldn't take place for another 13 years). English Wikipedia also seems to confuse some issues - he is described as having traveled to the Holy Land under Henry of Grosmont, Duke of Lancaster, but in Henry of Grosmont's page, he is described as having been on a Crusade in Prussia. The problem with this is that the Prussian Crusades had long since been over by 1352. The Swedes were carrying out a Crusade against the Orthodox of Novgorod around this time, but it seemed unlikely that an Englishman would be taking part in such a crusade (although not impossible). Further, neither Lundy nor FMG support a death location as taking place "on the way to the Holy Land" or Prussia, or Novgorod, etc. As an aside, a Black Death pandemic hit around the same time, but again, no documentation exists that links his death to this.

Burial: Rievaulx Abbey, Helmesley, Yorkshire (according to FMG, citing Dugdale Monasticon V, Rievall Abbey, Yorkshire, III, Fundationis et Fundatorum Historia, p. 281.)

Occupation: 3rd Lord Ros of Helmesley is his proper title. (A user originally had him as the 4th Baron Ros of Hamlake, apparently based on Jorge Castelli's Tudor Place naming him so, but this is without citations, and with other apparent errors.)

Alternate names: William de Ros.

From the English Wikipedia page on William de Ros, 4th Baron de Ros

William de Ros, 4th Baron Ros of Hamlake (1325 – 1352) was a military commander under Edward, the Black Prince. He was knighted by the Black Prince in 1346, having helped raise the siege of Arguillon. In the same year, he was one of the lords who led the second division in the Battle of Crécy, and afterwards commanded the fourth division of the English army against the Scots, near Neville's Cross, when David Bruce, with many of the Scottish nobles, was taken prisoner.

In 1348, he was with the Black Prince, at the siege of Calais, when it was taken by the English. In 1352, he accompanied Henry of Grosmont, Duke of Lancaster, to fight the Saracens; but died the same year, before the feast of St Michael, aged twenty-six, on his journey to the Holy Land, and was buried abroad. He married Margaret, daughter of Ralph, Lord Neville but died childless.
