Henry Monyash ruled 39 years 11 weeks (H83) from *1397 to *1436 (WARD, M, PAGE), *1400 to *1439.
 
‘Excellent in all honesty of manners’ (H83, C41).  (1379 ordained subdeacon.  1381 ordained deacon.  1383 ordained priest.)
  
1397 The King sent letters with the privy seal to the abbot of Dale asking him for the loan of wool to further the war with France (COX18).

1397 There was a commission to the abbot of Derby, the abbot of Dale and John Brewode clerk to enquire and certify touching the withdrawal, both in the times of Thomas de Goldyngton, Robert Sandford and other wardens, or in the time of the present warden, of prayers, suffrages and other works of piety usual in the hospital of St leonard, Derby, according to its primitive foundation.
 
1398 The dignity of papal chaplain was conferred on John Kirkeby, canon of Dale (COX18).

The church was valued at 40 marks (C41).

Dale Abbey had the right to appoint vicars of Ilkeston. Some time during this abbot's rule, the Pope appointed a John Aston to this post, whereupon the abbot appealed to the crown. Aston was imprisoned, but as he was unable to bail himself out, the king ordered him freed (20 Feb 1398).  He promptly returned to Ilkeston. The Bishop of Lichfield wrote to the king on 27 June, 1400 to get action and appears to have succeeded (more details in C41E).
Is this the same episode as the following entry?

1402 Pardon to John Wylehar chaplain, of his outlawry in co. Derby, for not appearing before the justices to answer to the King for being a maintainer and abettor of one John Orton, clerk, of the county of Nottingham, who caused a provision to be made to himself from the apostolic see of the church of Ilkeston, lawfully appropriated to the abbot and convent of Dale, contrary to the form of the ordinance in parliament of Edward III at Westminster, or to the abbot for the injury, he having surrendered to the Marshalsea prison, as William Gascoigne, the King’s chief justice, has certified (COX18).
