Name: Richard BEAUMONT , of Shirwell & Highampton, Sir 1
ALIA: Richard de /Bello Monte/, of Shirwell, Sir
Birth: ABT 1225 in Youlston Manor, Shirwell, Devon, England

NOTE: I have included various sources of my information below, which all pretty much agree with the descent from Richard down. However, the ancestry of Richard himself is open to question. Two of the sources below indicate a descent from the Vicomte du Maine family. I have the Beaumonts Vicomte du Maine in my files, complete with their ancestry, and they are at best distantly related, if at all, to the Beaumonts who were Earls of Leicester. The Vicomtes were of Beaumont-sur-Sarthe in Maine and the Earls were of Beaumont-le-Roger in Normandy, and the similarity of their names is only coincidental.
I am guided in my ancestry for Richard by the holding of Sherwell in 1086 by Robert Beaumont, 1st Earl of Leicester. I believe that the Beaumont family held Sherwell in all of the subsequent generations which leads me to follow the suggestion that the descent went through Hugh "the Pauper" Beaumont, Earl of Bedford. Very little is known of his later life and descendants (if any).
Two sources agree that Richard's father was Philip (wikipedia doesn't say), so he stays. Starting from Hugh the Earl of Bedford, I go with Sir William Pole's descent (Thomas & then John of Sherwell (he then follows with way too many generations for the years involved), then I go with Richard (but not a Vicomte) as father of Philip.
I don't have great sources on Devon in British History, but Magna Britannia, in its short history of Highampton does not mention any Beaumonts holding it, which makes me doubt whether they ever did (see notes for father Philip).
I received the following e-mail from Simon Young, who gives me corrections and suggestions from time to time:
The Beaumont family website contains the 1929 work on this family. The beaunmonts of Shirwell start with----
 Philip de Bellomonte Ld of Highampton. Who he was is not known. Roger de Meules held Highampton in 1086 but it is not known if there is any connection. Shirwell was held by Robert de Beaumont 1st Earl of Leics. the author makes a sort of inference that it may have come to his youngest son Hugh the Poor earl of Bedford and that Philip may have descended from him. But he does not push this and it seems unlikely as Hugh is only known to have one son Hugh who had a son Able and then the line disappears.If it were so it would mean his son would have md a 1st cousin which seems unlikely. Shirwell probably came into the family via his dr-in-law. His appellation of de Bellomonte may simply have come from his son's marriage and have been back dated as it were. On the other hand this Philip is very likely fictional. Henry usually md his illegitimate drs well and the traditional identification of Richard de Bellomonte is probably correct.
 Richard de Bellomonte of Highampton and Montrevaut. created 1st Viscomte presumably when he md Constance dr of Henry I by Elizabeth dr of Robert de Beaumont., 1st Earl of Leicester.
 Richard 2nd Viscomte
 Richard 3rd Viscomte bn at Youlston in the parish of Shirwell Devon
 Sir Philip Beaumont Ld of Highampton. Although he inherited most of the estates he did not inherit the title so he was presumably illegitimate.the title seems to have gone with Agnes his sister or half sister.
 Sir Richard Beaumont held Lokeshore and Chilton in Somerset and Witeston in 1285
 William Beaumont on 6th crusade with St Louis in 1249 md Margaret
 Richard Beaumont d 1294
 Sir John Beaumont d 12 Mar 1379/80 md 2nd Joan Crawthorne gddr & hr of Robert Stockey MP 1318. She later md Sir Walter Esturmay.
 Maud[Matilda]md Hugh Courtenay
 Katherine de 1431 md Hugh Luttrell
However as Matilda md 16 Oct 1417 and d 3 July 1467, Richardson is probably more correct when he identifies her in Magna Carta Ancestry as the dr of Sir John's son William Beaumont who md Isabel Willington dr of Sir John de Willington by Maud dr of Sir Walter Carminow.
The following is excerpted portions of the wikipedia article on the "Manor of Shirwell", which concerns the Beaumont family of Devon:
Beaumont of Beaumont-le-Roger, Normandy
In the Domesday Book of 1086 Ascerewelle (Shirwell) was one of at least four manors held in Devon, but merely as a mesne lord from Baldwin de Meulles, by the Norman magnate Robert de Beaumont, 1st Earl of Leicester, Count of Meulan (c. 1040/50-1118), to whom had been granted by William the Conqueror about 91 English manors in several counties for his service in the Norman Conquest of England. These four manors tenanted by Robert are listed consecutively within the section in Domesday Book listing Baldwin's holdings, as Shirwell, Ashford and two manors called Loxhore, thought to correspond to today's adjacent settlements of Higher Loxhore and Lower Loxhore....
The descent of Beaumont of Youlston, Shirwell is given in the Heralds' Visitation of Devon as follows:
- Sir Richard de Beaumont (13th century). The earliest positively identifiable descendant of the Domesday tenant Robert de Beaumont was the 13th-century Sir Richard Beaumont, whose family had long been seated at the capital estate of Youlston within the manor of Shirwell. His eldest son and heir was Philip Beaumont (d. circa 1272), of Youlston, and his younger son was William Beaumont, called in the Heralds' Visitation of Devon "of Sabrecot", to whom he granted the manor of Loxhore. Sabrecot appears to survive today as an estate calles Shepscott, about 3 miles south of Youlston, and 7 miles south-west of Loxhore Church, anciently known as Shebescote et al., and this branch of the family eventually inherited Shirwell also, on the failure of the senior male line.
- Philip Beaumont (d.circa 1272), eldest son and heir, of Youlston married Ermengard Punchardon, daughter and co-heiress of Sir John Punchardon of Heanton Punchardon in Devon. This family were listed in Domesday Book as de Pont-Chardon holding Hantone, also as tenants of Baldwin the Sheriff.
- Sir John Beaumont (d.1330), eldest son and heir, of Youlston, MP for Devon in 1326, who married Alice Scudamore.
- John Beaumont, son and heir, who married Alice, of unknown family.
- William Beaumont, only son and heir, who died without progeny leaving his sister Joan Beaumont as his heiress.
- Joan Beaumont (sister) was the wife of Sir James Chudleigh. She too died without progeny and the Beaumont estates, now enlarged by the addition of the Punchardon lands, passed to her cousin John Beaumont (d.1378/80), of Sepscott.
- John Beaumont (d.1378/80), of Sepscott, (cousin), was a grandson of William Beaumont, who had been granted Loxhore by his father Sir Richard Beaumont, and son of Richard Beaumont. John Beaumont married Joane Crawthorne (or Crawstone), the heiress of her grandfather Sir Robert Stockey, MP in 1318. He purchased the North Devon manor of Parkham.
- William Beaumont (son and heir), was Sheriff of Devon in 1399, and held the Castle and Borough of Barnstaple. He further increased the family's estates by marrying Isabel Willington, daughter of Sir John Willington of Umberleigh, and co-heiress of her brother John Willington (d.1396). The effigies of a Willington knight beside his Lady existed in Umberleigh Chapel prior to their removal to Atherington Church in about 1820, where they are visible today.
The following is what Sir William Pole, 'Collections Toward a Description of the County of Devon', 1791, had to say (many ancient spellings):
Thomas de Bello Monte [whom he states is somehow descended from the Vicomte who m. Henry I's illegitmate dau.], of Yolston, & lord of Sherwell, had issue John, who had Phillip, who had issue Richard & William. Richard had issue Sir Phillip, who had issue Sir Richard, who had issue Phillip, & William of Sebrescot. Phillip had issue by Ermegard, dau. & coheire of Sir John Punchardon, Sir John, who by Alis Scudamore had issue John, William, Richard, Lucia, Margaret, Matild, Katerin, & Alis. John Beaumont, by Alis his wife, had issue William, Joane, and Elisabeth. William & Elisabeth died without issue, in the life tyme of Alis their grandmother. Joane was maried unto Sir James Chidlegh, but died without issue; she conveyed her land unto Richard Beaumont & Sir John Beaumont his sonne, which Richard was sonne of William Beaumont, of Sebriscot, brother of Phillip of Sherwill. Sir John maried Joane, the heire of Crawthorn & Stockhey, & had issue William. The said Jone, after the death of Sir John Beaumont, was maried unto Sir William Esturmy. William Beaumont, sonne of Sir John, had unto his wife Isabel, sister & heire of Raph, & John Willington, & had issue Sir Thomas.
