Tyldesley was one of several lawyers to represent Derby during the Lancastrian period. It may be that he was a kinsman of the King’s serjeant-at-law, Thomas Tyldesley (d.1409) of Tyldesley and Eccles in Lancashire, but evidence is lacking and he was certainly not his son.
Little is known of the middle years of Tyldesley’s career, but in its later part he was involved in a series of local disorders. In the autumn of 1444 he was implicated in an act of disseisin at Stretton-en-le-Field (Derbyshire) committed in support of a leading townsman, John Booth*, who claimed to hold the manor there in right of his wife. In Easter term 1447, described as ‘of Derby, yeoman’, he was among 44 townsmen each fined 20s. in the court of King’s bench for unspecified trespasses.
The date of Tyldesley’s death is unknown, but probably occurred shortly before February 1457 when John Saynton* was appointed to his office of feodary. It is likely that Hugh Tyldesley, who, in 1469, made conveyance of a garden in Derby near Bag Lane, was his son, and John Tyldesley, coroner of Derby in the late 1470s, his grandson.
