"After the battle of Hastings, when England was parcelled out among the followers of the Conqueror, West Markham became the fee of Roger de Busli, who already held numerous estates in Nottinghamshire. Under de Busli it was held by Claron, whose family had been long resident there; and it was Claron's successors who adopted as their surname the place of their abode-"de Markham." Claron was succeeded in the landed possessions by his son Roger. There is little further known of these men in that early age, except that they were in possession of the lands, and that a "de-Markham" also held a Manor in " East Markham" in the reign of Henry the First.
The first man of note mentioned by the historian is Sir Alexander de Markham, who was born about 1130, and distinguished himself in the wars during the reign of Stephen. In the time of Henry the Second he was appointed constable of Nottingham Castle, which he held during the reign of Richard the First, and that of John.
Richard de Markham, living in the time of Henry the Third, shared with the family of Roland de Sutton in right of his mother all the vast possessions of the Lexington family; they being found the next heirs of the Bishop of Lincoln, who outlived his brothers.
Richard de Markham thus, besides other lands, held of the King in capite half a knight's fee and the culture and wood in Knesale, also in Stratham three cultures of John de Eyville. Richard de Markham left three sons, Robert, who succeeded him, Richard, and William."
