Such is the evidence for concluding that the custom of receiving children for education in nunneries was widespread. It remains to consider carefully the limitations within which this conclusion is true. In the first place, not all nunneries received children. It is obviously impossible, considering the gaps in our evidence, to attempt an exact estimate of the proportion which did so. Some sort of clue may be obtained by an analysis of the Yorkshire visitations of Archbishops Greenfield and Melton at the beginning of the fourteenth century (1306-20) and of Alnwick's Lincoln visitations (1440-5). The Yorkshire evidence is rather scanty, being based on the summaries of injunctions, which are given in the _Victoria County Histories_, and any statistics must needs be approximate only. The two archbishops between them visited nineteen nunneries and mention of children is made at twelve, i.e. about two-thirds. The information given by the invaluable Alnwick is more exact. From the _detecta_ of some of the nuns and from the number of prohibitions of this practice, it is obvious that Alnwick was accustomed to ask at his visitations whether children were sleeping in the nuns' dorter; he also made careful inquiry as to the boarders. The probability, therefore, is that we have in his register an exact record of those houses in which children were received. Analysis shows that of the twenty houses which he visited he found children, often boys as well as girls, at twelve, i.e. a little over two-thirds, which is substantially the same result as was given by the Yorkshire analysis a century earlier. The estimate is interesting, but it cannot be considered conclusive without the corroborative evidence from other dioceses, which is unfortunately lacking. It is a hint, a straw, which shows which way the wind of research is blowing, for if it is unsafe to argue from silence that the nuns of other convents did take pupils, it is equally unsafe to argue that they did not.
The fact is, however, clearly established that all nunneries did not take children; possibly about two-thirds of them did. The further fact has then to be recognised that even those nunneries had not necessarily what we should regard as a school for girls. Not only does it sometimes seem as though children were taken occasionally and intermittently, rather than regularly, but the numbers taken were rarely great. Sometimes we do hear of a house with a large number of pupils. At St Mary's Winchester in 1536 there were as many as twenty-six children, to twenty-six nuns; and at Polesworth in 1537 Henry VIII's commissioners state vaguely that "repayre and resort ys made to the gentlemens childern and studiounts that ther doo lif, to the nombre sometyme of xxx{ ti} and sometyme xj{ ti} and moo." There were fifteen nuns in the house at the time and it is likely that the number of children given is a pardonable exaggeration by local gentlemen who were interested in preserving the nunnery; but it seems undoubted that there was a comparatively large school there. At Stixwould, again, in 1440 there were about eighteen children to an equal number of nuns. These, however, are the largest schools of which we have record. At St Michael's Stamford in 1440 there were seven or eight children to twelve nuns, at Catesby in 1442 six or seven children to seven nuns. At Swaffham Bulbeck, where there were probably eight or nine nuns, there were nine children in 1483. These also are schools, though small schools. But at other houses there were only one or two children at a time. The accounts of the Prioress of St Helen's Bishopsgate in 1298 mention only two children, there were only two at Littlemore in 1445 and two at Sopwell at the time of the Dissolution. It must be remembered that many nunneries were themselves very small and their inmates could not have looked after a large number of children. The examples quoted above suggest that the number of children hardly ever exceeded the number of nuns. To what conclusion are we driven when we find that a possible two-thirds of the convents of England received children and that the largest school of which we have record numbered only twenty-six children (or thirty if we take the higher and less probable figure for Polesworth), while most had far fewer? Surely to represent a majority of girls, or even a majority of girls of gentle birth, as having received their nurture in convents, would be on the evidence absurd.
