That the custom of receiving schoolgirls was fairly general appears from the wide area over which notices of such children are spread. The references range in date from 1282 to 1537; they give us, if a doubtful reference to King's Mead, Derby, be accepted, the names of forty-nine convents, which at one time or other had children in residence. These convents are situated in twenty-one counties. The greater number of references naturally occur in those dioceses for which the episcopal registers are most complete; Yorkshire affords fifteen names and two which are doubtful; Lincolnshire, Northamptonshire, Buckinghamshire, Bedfordshire, Oxfordshire, Hertfordshire and Leicestershire, counties in the large Lincoln diocese, afford seventeen between them, five from Lincolnshire and two from each of the others. These references do not prove that the houses in question had continuously throughout their career a school for girls; sometimes only one or two children are mentioned and usually the evidence concerns but a single year out of two and a half centuries. Sometimes, however, a happy chance has preserved several references to the same house, spread over a longer period, from which it is perhaps not too rash to conclude that it was the regular practice of that house to receive children. For Elstow, for instance, there is an early reference to a boy of five sent there for education by St Hugh, Bishop of Lincoln, towards the close of the twelfth century. In 1359 Bishop Gynewell prohibited all boarders there, except girls under ten and boys under six. In 1421 Bishop Flemyng prohibited all except children under twelve and in 1432 Bishop Gray altered this to girls under fourteen and boys under ten, and children are mentioned at Alnwick's visitation in 1442. Similarly at Godstow there are references to children in 1358, 1445 and 1538, at Esholt in Yorkshire in 1315, 1318 and 1537, at Sopwell in 1446 and 1537, at Heynings in 1347, 1387 and 1393, at Burnham in 1434 and 1519.
The mention of boys in these references needs perhaps some further emphasis, for it is not usually recognised that the nunneries occasionally acted as dame-schools for very young boys. "Abstinence the abbesse myn a.b.c. me taughte," says Piers Plowman, "And conscience com aftur and kennide me betere." It is true that a Cistercian statute of 1256-7 forbade the education of boys in nunneries of that order[879], but the ordinance soon became a dead letter, and five of the convents at which Alnwick found schoolboys (c. 1445) were Cistercian houses. Boys were specifically forbidden at Wherwell in 1284, at Heynings in 1359 and at Nuncoton in 1531, which argues that they were then present, and they are mentioned at Romsey (1311), at five Yorkshire convents (1314-17), at Burnham (1434), at Lymbrook (1437), at Swaffham Bulbeck (1483) and at Redlingfield (1514), a chronologically and geographically wide range of houses. Occasionally some details as to a particular boy may be gleaned; the five year old Robert de Noyon, sent by Bishop Hugh to Elstow "to be taught his letters," the two Tudor boys commended to Katharine de la Pole, the noble Abbess of Barking; the little son and heir of Sir John Stanley, who made his will in 1527 and then became a monk, leaving the boy to be brought up until twelve years of age by another Abbess of Barking, after which he was to pass to the care of the Abbot of Westminster; and Cromwell's son Gregory and his little companion, sent to be supervised, though not taught by Margaret Vernon, Prioress of Little Marlow[880]. But as a rule the boys in nunneries were very young; it was not considered decorous for them to stay with the nuns later than their ninth or tenth year; the bishop forbade it and besides, the education which the good sisters could give them would not have been considered sufficient. The rule which gives a man child to a man for education is of very old standing.
