This is what I read, been trying to get a source though.

A Dynasty of seventeen Kings from Henry II through Richard III, who was killed while fighting the outnumbered forces of Henry Tudor in the Battle of Bosworth Field on August 22, 1485. That began the Tudor Dynasty.
Jean ( John, Johannes ) de Beaugency, Seigneur de La Fleche was born November 1, 1030, died in 1097 in St Aubon, Alpes de Haute ( Cote d'Azur ) Provence, France. He was a Norman French noble of Sarthe, France, who served under and was granted lands by King William I, the conqueror of England in 1066, Duke of Normandy.
Jean was the youngest son of Lancelin I de Beaugency and Mathilde de Chateau du Loir. Jean married Paula du Maine, daughter of Herbert I, Count of Maine. Jean and Paula are the parents of Helias ( Elias I ) de La Fleche, Count of Maine born about 1059 in Maine et Loire, Pays de La Loire, France, died July 11, 1110 in Angers, Maine et Loire, Anjou, France, who married the Countess Matilda, daughter of Gervais II, Lord of Chateau du Loir and they had a daughter Ermengarde de La Fleche, she married Foulques V ( Fulk V ), 9th. Count de Anjou, who became King of Jerusalem in 1131 following the First Crusade. They are the parents of Geoffrey Plantagenet, he married the Empress Matilda, daughter of King Henry I of England ( son of King William I ) in 1128. This was a very dangerous alliance for King Louis VI of France and would prove so during the reign of his son and successor, King Louis VII. Geoffrey Plantagenet was knighted by his father in law King Henry I. Geoffrey Plantagenet and Empress Matilda's son was King Henry II of England, who is the great great grandson of Jean de Beaugency, Seigneur de La Fleche. King Henry II married Eleanor ( Elena ) of Aquitaine, who was Queen consort of France from 1137 to 1152 and England from 1154 to 1189 and Duchess of Aquitaine in her own right.

Jean de Beaugency, Seigneur de La Fleche appears to be the forefather of all the Fletcher's of the British Isles and beyond, he is of Norsemen ( Viking ) descendant.
Fletcher's can be found in France, England, Wales, Scotland and Ireland.
The Fletcher's were first established in the Forest of Hutton in York, England. Near the Village of Skelton in a field is the small Church of St. James, recorded as far back as 1291 as the Church in the Green Field. A fragment of a Norman Cross is preserved within the church and many memorials act as reminders of the influence of the Fletcher's and Vane's over the centuries.
One of Jean de La Fleche’s descendants, Sir Bernard Fletcher ( possibly the son of Helias ( Elias I ) de La Fleche ), moved north and received lands in Roxburghshire by King David I of Scotland, who reigned from April or May 1124 to May 24, 1153. They later moved further north to Aberdeen and were some of the first settlers in Glenorchy, making an alliance with the Scottish Stewart's ( Stuart's ) and later the Campbell's after several ordeals, who's clan dominated the Glenorchy region.
( Note: King David I of Scotland, is the half brother of Matilda ( Edith ) of Scotland, first wife of King Henry I of England, son of King William I of England, the Conqueror of 1066. King David I and Matilda of Scotland are the children of King Malcolm III of Scotland. King Henry I of England and Matilda of Scotland’s daughter Empress Matilda married Geoffrey Plantagenet, Count of Anjou, who are the parents of King Henry II of England. Geoffrey Plantagenet is the great grandson of Jean de La Fleche and Paula du Maine.)
The next oldest records of Fletcher's found in England as of now, are of Robert le Flecher in 1203, in the “ Assize Court Rolls of Staffordshire ”, during the reign of King John, known as “ Lackland ”, who reigned from April 6, 1199 to his death in 1216.
Plea Roll 82 for Staffordshire 1244 to 1250 Staff.
There is an ancient town in France name La Fleche
Fletcher is an occupational name of the makers and sellers of arrows.
Which means a person who makes and sells arrows, had the title as a Fletcher, it does not mean that a person who makes and sells arrows had the surname Fletcher. All of the early Fletcher's found are being proven to be descendants of Jean de La Fleche.
