Arrival in England Flaad and his son Alan had come to the favourable notice of King
Henry I of England who, soon after his accession, brought Flaad and Alan to England. Eyton, consistently following the theory of the Scottish origins of the Stewarts, thought this was because he was part of the entourage of the Queen,
Matilda of Scotland; Round pointed out that Henry had been besieged in
Mont-Saint-Michel during his struggle with his brothers, an event which probably occurred in 1091. He is known to have recruited Breton troops at that time and, after his surrender, left the scene via the adjoining regions of Brittany, where Dol is situated. This is a likely explanation for the Bretons in the military retinue he brought to England after the death of
William Rufus. Alan's career in England can be traced largely through his presence as a witness to charters granted by the king during his travels in the first decade or more of his reign. Some of his activities were traced by Eyton, and his researches overlap with William Farrer's calendar of Henry I's travels. All of the business in which he took part was ecclesiastical, involving grants, sometimes disputed, to churches and monasteries.
Appearances at court , showing Henry enthroned and symbolically holding a church. Alan fitz Flaad's business at court seems invariably to have involved donations to the church. Alan appeared in Henry I's company at least as early as September 1101, probably at a court held in
Windsor Castle, when he witnessed important grants to
Norwich Cathedral, confirming its foundation and various endowments. Next, he appeared with the king at Canterbury in 1103, where he witnessed the grant of a market to the nuns of
Malling Abbey and land acquisitions by
Rochester Cathedral, then in the process of rebuilding. Later that year, or early in the next, Alan was with the king in the
New Forest, where the business concerned
Andover Priory, a daughter house of the great
Benedictine Abbey of Saint-Florent de Saumur. He was probably selected deliberately for this meeting because of his family's close connections with Saumur Abbey: one of his uncles was a monk there. One problem at issue revolved around the Foxcote chapel, which was evidently being defended from destruction or annexation by Edward de Foscote, a local landowner. Another seems to have been the administration of justice in the monastic estates. Wihenoc, a monk of St Florent, had initiated an action against the
reeve of Andover to have these issues clarified and resolved. Alan Fitz Flaad was called upon to witness a compromise, although Foxcote was among the properties confirmed to the priory by Pope Eugenius III in 1146. In the autumn of 1105, Alan was called to
York to witness confirmation of
Ralph Paynel's transfer of his refounded
Holy Trinity Priory in York to
Marmoutier Abbey, Tours and his many endowments of the priory itself. At some point, he also witnessed Roger de Nonant's gift of the church at
Totnes and various tithes to the Abbey of Ss
Sergius and Bacchus at
Angers, a gift earmarked as being for the souls of the royal family. In May 1110, Alan was at court at Windsor again to witness the king's settlement of a property dispute between
Hervey le Breton,
Bishop of Ely, and
Ranulph Flambard,
Bishop of Durham, resolved in favour of the former. Probably only later did he appear as a witness to a royal command issued to
Richard de Belmeis I, the
Bishop of London and the king's viceroy in Shropshire, to see that justice was done in the case of a disputed
prebend at
Morville. The
collegiate church there had been dissolved and replaced with a priory attached to
Shrewsbury Abbey and it seems that the son of one of the prebendaries was resisting the loss of what he regarded as his patrimony. Alan is listed among a group of Shropshire magnates, including
Corbets and a Peverel, meeting perhaps during Henry I's
1114 military expedition into Wales. Johnson and Cronne tentatively place the meeting at
Holdgate Castle in Shropshire. Eyton dates the event earlier, around the time of a royal expedition to Shropshire in 1109. Whatever the date, it shows Alan as an important member of the Shropshire landowning class.
Territorial magnate Alan's rapid ascent to wealth and power was a symptom of troubled times. The abortive revolt of
Robert de Belleme in 1102 had torn apart the Anglo-Norman system of governing the
Welsh Marches. With other Breton friends, Alan had been given forfeited lands in
Norfolk and
Shropshire, including some which had previously belonged to Robert de Belleme himself. Robert had proved a threat to Henry in both the
Welsh Marches and in Normandy, so the king was determined to insert reliable supporters to counterbalance or replace his network of supporters. Alan received more land as he proved his worth. A large portfolio of lands in Shropshire and around Peppering, near
Arundel in Sussex, was taken from the holdings of Rainald de Bailleul, ancestor of the
House of Balliol, which was also later to provide a king of Scotland. These were lands granted to Rainald by
William the Conqueror in recognition of his role as
Sheriff of Shropshire. There is no evidence that Rainald or his successor, Hugh, were rebels, and it seems that their lands came to Alan because of his elevation to the shrievalty of the county. He also gained a stake in the very large estates of
Ernulf de Hesdin by marriage to his daughter, Avelina. ==Religious grants and foundations==
